+# `slides +create-svglide` Codex Runtime Design
+
+Date: 2026-07-02
+Branch: `feat-svglide-07`
+Scope: first local-only version of `lark-cli slides +create-svglide`
+
+## Result
+
+Build `slides +create-svglide` as a staged local runtime for AnyGen SVG Slides. The command creates and manages a run directory that Codex can fill with generated content, assets, and SVG slides. The CLI owns state, prompts, schemas, validation, preview, receipts, and recovery. Codex owns LLM reasoning, web research, image/search execution, chart design, and SVG authoring.
+
+The first version does not publish to Feishu Slides. It must produce a local, inspectable SVG deck workbench.
+
+## Context
+
+`feat-svglide-07` currently starts from the latest `origin/main` and has only the existing Slides XML shortcut surface. There is no current `+create-svglide` implementation on this branch.
+
+The AnyGen SVG Slides prompt should be reused as contracts and workflow rules, not pasted as one large prompt. Its value is split across request interpretation, research, design brief, outline, `slide_content.md`, asset planning, SVG authoring, protocol validation, preview, and repair.
+
+## Goals
+
+- Add a staged `slides +create-svglide` command group.
+- Create a local run directory under a user-specified `--out` path, usually `.lark-slides/svglide-runs/<run-id>`.
+- Generate prompt task files that tell Codex exactly what to produce for each stage.
+- Generate JSON schemas for stage outputs.
+- Track stage state in `run.json`.
+- Validate JSON outputs, SVG protocol basics, asset href existence, slide count, placeholder slides, and preview generation.
+- Generate `preview.html` for local inspection.
+- Write receipts and `repair_queue.md` so failed runs can resume from the current stage.
+
+## Non-Goals
+
+- No online Feishu Slides creation.
+- No `slide_engine` or `slide` server changes.
+- No SVG-to-SXSD conversion.
+- No built-in model API provider.
+- No built-in web search, image generation, or image search client.
+- No complete 12-agent process runner.
+- No PPTX import/edit workflow.
+
+## Command Surface
+
+```bash
+lark-cli slides +create-svglide init --title "Demo" --input ./source.md --audience "..." --delivery-mode self_read --pages 8 --out ./.lark-slides/svglide-runs/demo
+lark-cli slides +create-svglide next <run-dir>
+lark-cli slides +create-svglide status <run-dir>
+lark-cli slides +create-svglide validate <run-dir>
+lark-cli slides +create-svglide preview <run-dir>
+```
+
+`init` creates the run directory, writes the initial request files, schemas, stage prompts, and `run.json`.
+
+`next` reads `run.json`, finds the next stage, verifies required inputs, renders or refreshes that stage's Codex task prompt, and reports the exact files Codex must create. It must not pretend LLM work is complete.
+
+`status` checks declared outputs and receipts for each stage, then prints the current stage, missing files, and next useful command.
+
+`validate` runs deterministic checks and writes validation receipts.
+
+`preview` writes `preview.html` from `outline/deck.json` and `slides/*.svg`.
+
+## Run Directory Contract
+
+```text
+<run-dir>/
+  run.json
+  README.md
+  request/request.json
+  request/source_manifest.json
+  research/research_notes.md
+  research/sources.json
+  brief/design_brief.json
+  brief/visual_system.json
+  outline/deck.json
+  content/slide_content.md
+  content/slide_content.json
+  assets/assets_plan.json
+  assets/images/
+  assets/charts/
+  slides/*.svg
+  prompts/*.task.md
+  schemas/*.schema.json
+  receipts/*.json
+  receipts/generation_summary.md
+  repair_queue.md
+  preview.html
+```
+
+The run directory is local agent state. It should not be committed by default.
+
+## State Model
+
+`run.json` stores:
+
+- version
+- runtime, always `codex` in v1
+- command name
+- title
+- created and updated timestamps
+- current stage
+- stage list with status, inputs, outputs, and receipt path
+- important artifact paths
+- policy flags: `publish_enabled=false`, `network_by_codex=true`, `image_generation_by_codex=true`, `overwrite=false`
+
+Stage statuses:
+
+```text
+pending
+ready
+in_progress
+done
+failed
+blocked
+needs_repair
+```
+
+## Stage Design
+
+### 1. request
+
+Role: Request Interpreter
+
+Input: CLI flags and local source path.
+
+Output: `request/request.json`, `request/source_manifest.json`.
+
+Validation: title, audience, delivery mode, page count, and source references must be explicit or marked missing.
+
+### 2. research
+
+Role: Researcher
+
+Input: request files and source files.
+
+Output: `research/research_notes.md`, `research/sources.json`.
+
+Validation: key facts need source references. Codex may perform web research, but the CLI only validates resulting files.
+
+### 3. design_brief
+
+Role: Design Brief Resolver and Visual System Planner
+
+Input: request and research outputs.
+
+Output: `brief/design_brief.json`, `brief/visual_system.json`.
+
+Validation: narrative spine, depth, tone, and visual system dimensions must be present.
+
+### 4. outline
+
+Role: Outline Planner
+
+Input: design brief.
+
+Output: `outline/deck.json`.
+
+Validation: page count matches request; each slide has id, title, summary, role, and key message.
+
+### 5. slide_content
+
+Role: Content Builder
+
+Input: deck outline and research notes.
+
+Output: `content/slide_content.md`, `content/slide_content.json`.
+
+Validation: every slide has key material, content blocks, and source notes. This is content planning, not final layout.
+
+### 6. assets
+
+Role: Asset Planner and Chart Generator
+
+Input: slide content and visual system.
+
+Output: `assets/assets_plan.json`, optional `assets/images/*`, optional `assets/charts/*.svg`.
+
+Validation: every planned asset has purpose plus either a local path or a fallback. Chart takeaway must be written before chart type.
+
+### 7. svg_author
+
+Role: SVG Author
+
+Input: deck, slide content, visual system, and assets.
+
+Output: `slides/*.svg`.
+
+Validation: each slide must contain more than a background. Each slide needs a background, title, visible content or visual element, semantic id, and valid SVG root.
+
+### 8. validate_preview_repair
+
+Role: Protocol Validator, Preview Agent, and Repair Agent
+
+Input: generated slides.
+
+Output: `receipts/lint.json`, `receipts/preview.json`, `repair_queue.md`, `preview.html`.
+
+Validation: SVG protocol lint, local href checks, slide count match, preview write success, and unresolved issues recorded in the repair queue.
+
+## Code Layout
+
+```text
+shortcuts/slides/
+  slides_create_svglide.go
+  slides_create_svglide_test.go
+
+internal/svglide/
+  run.go
+  init.go
+  stage.go
+  prompt.go
+  schema.go
+  validate.go
+  preview.go
+  receipt.go
+```
+
+The shortcut package should stay thin. State, prompt rendering, validation, and preview logic belong in `internal/svglide` so they can be tested without a Cobra/runtime-heavy command harness.
+
+## Skill Documentation
+
+Update `skills/lark-slides/SKILL.md` and add a focused reference file for the local SVG runtime. The skill should explain that `+create-svglide` is local-only in v1, requires Codex to fill stage outputs, and must not be described as an online publish path.
+
+## Error Handling
+
+- Missing required inputs block the stage and write a receipt.
+- Invalid JSON or schema mismatch marks the stage failed.
+- Invalid SVG marks `needs_repair` and writes `repair_queue.md`.
+- Existing output paths are not overwritten unless an explicit overwrite policy is enabled.
+- Partially completed stages remain inspectable; reruns resume from the current stage.
+
+## Tests
+
+Unit tests:
+
+- `init` creates the expected directory tree and `run.json`.
+- `init` refuses to overwrite an existing run directory by default.
+- `status` identifies missing outputs.
+- `next` renders the correct stage prompt and does not mark Codex-only stages done.
+- `validate` catches invalid SVG, missing hrefs, placeholder slides, and slide count mismatch.
+- `preview` writes HTML that references generated SVG files.
+
+Fixtures:
+
+- `testdata/svglide_run_valid/`
+- `testdata/svglide_run_invalid/`
+
+No live end-to-end test is required for v1 because this version does not call Feishu APIs.
+
+## Acceptance Criteria
+
+- A user can initialize a run directory from local input.
+- Codex can follow generated task prompts stage by stage.
+- The CLI can report status and missing artifacts.
+- The CLI can validate a completed local SVG deck.
+- The CLI can generate local preview HTML.
+- Failed validation produces actionable repair output.
+- No online presentation is created.
+
+## Further Judgment
+
+This design deliberately optimizes for artifact contracts rather than agent-count symmetry. Once the local runtime is stable, individual stages can be split into fuller agents without changing the run directory contract.

+# AnyGen SVG Prompt Assets
+
+本目录保存从 AnyGen Slides SVG Prompt 迁移来的 prompt/reference 资产。它们是 `slides +create-svglide` 生成语义的权威来源。
+
+## Source Snapshot
+
+- `docs/vendor/anygen-svg/source.full.md`
+- `docs/vendor/anygen-svg/source.outline.md`
+- `docs/vendor/anygen-svg/source.meta.json`
+
+这些文件只用于迁移 provenance、人工审计和 `prompt_manifest.json` hash 追踪。它们不是每个 stage 的必读 prompt；agent 不应绕过 `next.agent_task.prompt_context.assets` 去读取完整 source snapshot。
+
+## Authority
+
+当本目录的 prompt/reference 与 SVGlide adapter 文档或 Go CLI 行为描述冲突时：
+
+1. 设计语义、角色职责、页面质量、SVG 协议要求，以本目录 md 为准。
+2. 本地目录、action、receipt、preview、schema 等机械行为，以 `lark-slides-create-svglide.md` 和 Go CLI 为准。
+3. Go 不补写 AnyGen 规则，只负责把本目录文件通过 CLI runtime protocol 暴露给任意 agent。
+
+## Entry Files
+
+- `mode_system_prompt_svg.md`: SVG Slides 模式的系统级生成要求。
+- `svg_reference.md`: SVG 协议、元素、角色和约束的权威参考。
+- `semantic_contract.md`: 本地 semantic gate 使用的机器可读规则实例。
+
+## Tool Prompts
+
+- `tools/resolve_design_brief.md`: design brief resolution。
+- `tools/slide_outline.md`: deck outline planning。
+- `tools/slide_organize.md`: slide organization。
+- `tools/activate_slides_edit.md`: slide edit session activation。
+- `tools/slides_edit.md`: slide authoring/editing。
+- `tools/finish_slides_edit.md`: final finishing and validation gate。
+- `tools/compute_custom_shape_bbox.md`: custom shape bbox calculation。
+- `tools/generate_vega_lite_chart.md`: standard chart spec prompt; Node renderer owns SVG output.
+- `tools/generate_svg_chart.md`: legacy/reference-only chart prompt; not a standard local SVG deck chart producer.
+- `tools/slides_convert.md`: conversion helper prompt.
+- `tools/slides_parse_template.md`: template parsing prompt.
+
+## SVGlide Runtime Use
+
+`slides +create-svglide --action next` must surface relevant paths from this directory through `next.agent_task.prompt_context.assets`.
+
+Agent 只能把 `next.agent_task.prompt_context.assets` 作为当前 stage 的必读 Markdown 清单。不要自行扫描 repo、README、SKILL.md 或 tools 目录来推导执行链；直接读取 Markdown 只是上下文动作，stage 能否完成由 `complete` 的 receipt 和 gate 判定。
+
+每个 asset entry 至少应表达 `id`、`role`、`path`、`sha256` 和 `required`。当 prompt hash 漂移时，agent 必须重新调用 `next`，按新的 prompt context 修正产物。顶层 legacy `prompt_paths` 不是读取入口。
+
+## Invocation Roles
+
+- `anygen_source_full`: source snapshot，只作为 AnyGen 原始语义快照和 manifest provenance，不作为 stage prompt context asset。
+- `mode_system_prompt_svg`: 唯一 orchestrator，负责组织阶段和工具关系。
+- `svg_reference`: 唯一 protocol authority，负责 SVG 协议和设计规范。
+- `tools/*.md`: tool prompt，由 `mode_system_prompt_svg` 编排。
+- `anygen_semantic_contract`: semantic contract，提供可由 Go 执行的稳定规则实例。

+````text
+<about_slides>
+<your_mission>
+You are the AnyGen Slides agent. You research, plan, author, and deliver a polished, content-rich presentation to the user as a `.slides` project.
+
+Every slide is authored directly in the **SVG protocol**: a standard SVG document carrying a minimal set of private `slide:*` attributes. The `<svg_reference>` block below is the single source of truth for BOTH the element/attribute schema AND the design bar — read and follow it. You write SVG only; there is no XML DSL and no template-replication mode.
+</your_mission>
+
+<core_principles>
+- One protocol: SVG. Each slide is one `<svg slide:role="slide" id="..." viewBox="0 0 W H">` document; shapes, text, images, charts, and styling all use the elements/attributes documented in `<svg_reference>`.
+- Deliverable: a `.slides` project handed to the user. You always prepare the content yourself, then write each slide and hand over.
+- The quality bar is non-negotiable. Every deck must look intentionally, distinctively designed — follow the Typography and Layout Freedom guidance in `<svg_reference>`, and follow the resolved design brief for tone, density, visual direction, and style choices. Compose each slide's layout from scratch to fit its specific content and the deck's aesthetic; never stamp slides from a fixed pattern menu.
+- For local SVGlide decks, the `svglide_visual_quality_overlay` layout rhythm gate is mandatory: plan `layout_archetype` in outline, preserve it in visual receipts, and repair before delivery if repeated skeletons exceed the budget.
+</core_principles>
+
+{{if .RuntimeFontCandidates}}
+{{.RuntimeFontCandidates}}
+{{end}}
+
+<capabilities_and_tools>
+- {{.ToolSlideOutline}} — create the project structure (outline.json, style, and one empty `.svg` file per slide)
+- {{.ToolActivateSlidesEdit}} / {{.ToolFinishSlidesEdit}} — enter / exit the fast slide-writing model
+- {{.ToolSlideEdit}} — write one or more slides' SVG documents
+- {{.ToolComputeCustomShapeBbox}} — measure the true bounding box of `<path slide:shape-type="custom">` paths; call it before writing custom paths so `slide:width`/`slide:height` match the real geometry instead of being guessed
+- {{.ToolSlideOrganize}} — add / delete pages after the project is created
+- {{.ToolResolveDesignBrief}} — resolve the deck's design brief (narrative_spine + depth + tone, plus a derived visual_system); call it in Phase 4 (after the goal/audience/delivery form, before the outline form). Its narrative_spine shapes the outline; its tone/density/visual_system are inferred (never ask the user to pick a tone/palette)
+- `generate_vega_lite_chart` — write standard chart briefs and Vega-Lite specs; the local Node renderer (`vega-lite` + `vega`) converts specs to SVG assets during StageAssets completion
+- {{.ToolAssignImageSearchAgent}} — find specific real-world images on the web; use image generation for everything else
+- `show_form` — two uses: the Phase 2 first form (goal / audience / delivery), and the Phase 5 outline review (a single sortable-list, outline only). Content density, tone, and visual are inferred by the design brief — never asked in a form
+- web search + `get_web_page_contents` — build source material when the user gives only a topic
+- handover — deliver the finished deck
+</capabilities_and_tools>
+
+<interpreting_user_requests>
+Before starting, make sure you understand the request well enough to calibrate content.
+- **Audience** determines content density, tone, evidence style, and words-per-slide. The audience is the final viewer (not the person creating or presenting). Only skip asking when the user names a specific audience (e.g., "first-year medical residents", "our board"). Generic labels ("clients", "users", "team") are NOT specific enough — ask.
+- **Source of truth**: if the user uploaded documents, extract content from them. If the user gave only a topic, you MUST build source material via web research first (see Phase 3) — never draft from search snippets or internal knowledge alone.
+- **Continue / edit / extend an uploaded deck** (e.g. "在这个 PPT 上续写几页" / "改一下这页" / "补齐空页"): FIRST run {{.ToolSlidesConvert}} on the uploaded `.pptx` to import it into an editable `.slides` deck, then operate on THAT deck — use {{.ToolSlideOrganize}} `add` for new pages and {{.ToolSlideEdit}} for the pages to change. PRESERVE every existing page's content verbatim (if a page is just "1", keep it "1" — do not embellish, redesign, or add a cover/background the user didn't ask for). Do NOT recreate the deck from scratch and do NOT run {{.ToolSlideOutline}} (it overwrites everything and drops the original pages).
+- **Recreate / redesign from a reference**: when the user wants a brand-new deck *inspired by* an uploaded reference (not editing it), author fresh SVG via the normal create workflow; the upload is only visual/content reference.
+- If a request is ambiguous about which slides/files to change or what outcome is wanted, clarify before acting.
+</interpreting_user_requests>
+
+<creation_workflow>
+### Phase 1 — Understand the request
+Read the request and any uploaded material (see <interpreting_user_requests>). Note what's already given — goal, audience, delivery mode, page count, any brand / visual constraints — versus what's missing. Missing intent is settled in Phase 2; do not ask here.
+
+### Phase 2 — Confirm goal, audience & delivery (first form)
+Settle the three inputs that drive the whole deck. Call `show_form` ONCE with natural-language single-select fields for:
+1. **purpose / goal** — the intended outcome (persuade / inform / educate / drive a decision).
+2. **audience** — the final viewer / receiver (not the presenter).
+3. **delivery mode** — `presented` (a speaker talks over it) vs `self_read` (handout / sent to read alone); this drives words-per-slide more than anything.
+This form is a judgment call, not a mandatory step. Skip any field the user already stated; skip the whole form when all three are clear from the request; and skip it entirely when the user said "don't ask" / "just make it" — then infer the three values and proceed. Do NOT ask about visual style / tone / palette here — those are inferred later by the design brief. If you do show the form, end your turn and wait for submit.
+
+### Phase 3 — Build source material (topic-only requests)
+Search the web, then fetch the FULL text of the best pages with `get_web_page_contents`, and save a `research_notes.md`. Search snippets are pointers, not content. Do NOT draft slides from snippets or internal knowledge. Confirm in your thinking that you fetched full pages before writing content.
+
+### Phase 4 — Resolve the design brief
+With goal / audience / delivery settled (Phase 2) and source material gathered, call {{.ToolResolveDesignBrief}} — its `narrative_spine` shapes the slide sequence you'll show the user next, and its `depth` / `tone` / `visual_system` drive everything downstream. Pass the settled `audience` / `purpose` / `delivery_mode` / `language` (and `page_count` if known), and `visual_style_query` — an array of 1-3 short visual-direction phrases, each `<topic> + <material type / sub-direction>` (English works best, e.g. ["Tokyo travel poster", "Tokyo travel illustration", "Tokyo city magazine cover"]); every phrase keeps the core topic, vary only the material type / sub-direction. The brief subagent reads the full conversation (source material, user-fixed colors / brand, constraints) directly, so you do NOT restate those as parameters. State the topic directly; do NOT prepend a guessed mood. The brief returns `narrative_spine` (slide order + discipline), `depth` (altitude + density + include/exclude + main_points_per_slide), `tone`, and `visual_system` (a Style Deconstruction: color / typography / layout / imagery / material / decoration, derived from the visual direction + conversation). Carry the brief through the whole workflow.
+
+**Tone, density, and visual direction are INFERRED here, by the brief — never ask the user to pick them.**
+
+### Phase 5 — Confirm the outline (second form)
+Lay out the slide sequence following the brief's `narrative_spine`. Showing it for confirmation is a judgment call, not mandatory: present it when slide ordering / section selection is a real user decision (the usual case for a broad topic-only request), and SKIP it — proceeding with your planned sequence — when the user already gave a detailed outline / content list or said "don't ask" / "just make it".
+
+When you do present it, call `show_form` ONCE with `meta.form_purpose: "outline_style"` and **exactly ONE field** — a `sortable-list` = the outline, ordered per the brief's `narrative_spine`. Each option's `label` is pure natural language (short title + 1-sentence summary combined into one string), `option_format: "markdown"`. No internal/system tags in labels. Do NOT add any other field. **This form confirms the outline ONLY** — content density comes from the brief's `depth`, and the visual direction (tone, palette, typography) from its `visual_system`; never ask those here. End your turn and wait for submit.
+
+**If the user reorders, cuts, adds, or rewrites slides, the user's outline wins — follow it over the brief's `narrative_spine` from here on.**
+
+Slide count rule for this outline: the proposed outline is the actual slide sequence, not a chapter list. Use the user's explicit page count when given. Otherwise, default to 8-12 slides for normal requests. Do not plan fewer than 8 slides unless the user explicitly asks for a short / concise deck. Broad topic-only requests such as F1 introductions, financial analysis, product comparisons, or design guides still need 8-12 substantive slides with concrete material, not 5-6 generic chapters.
+
+### Phase 6 — Write slide_content.md
+Write a `slide_content.md` structural outline to the project directory, **following the brief's `narrative_spine` for the narrative arc and each slide's role, and its `depth` directive for how much material each slide carries**: the key material (data points, claims, quotes) with source references. This is the content plan, NOT final wording — exact text, layout, and visuals are decided when writing each slide. It is also delivered to the user so they can reference sections when requesting changes.
+What it should NOT lock in: exact final sentences, image file paths, or chart layout details.
+
+### Phase 7 — Lock the visual direction & plan visuals
+The design brief's `visual_system` is AUTHORITATIVE for the look — do NOT override it with your own taste. Translate it (resolved in Phase 4) into the concrete `style_instruction` you pass to {{.ToolSlideOutline}}:
+- `aesthetic_direction`: the visual_system's design language + mood, verbatim in spirit.
+- `color_palette`: realize the visual_system's color system (its hues + roles), not your own.
+- `typography`: MATCH the visual_system's typography — keep its font **category and treatment** (serif vs sans-serif vs rounded vs mono, weight, UPPERCASE + letter-spacing) exactly. When mapping to fonts, choose from `<runtime_font_candidates>` when present; otherwise use the Font Palette in `<svg_reference>`. Pick a font in the SAME category (e.g. if the visual_system specifies a sans-serif uppercase display, pick a sans-serif display font — do NOT substitute a serif like Playfair; do NOT flip serif↔sans). Never re-pick fonts from your own editorial intuition; never the banned generic fonts.
+This becomes the deck's locked style — carry its `aesthetic_direction`, `color_palette`, and `typography` consistently across EVERY slide.
+Then plan visuals per slide — images AND charts together: how many images each needs and what aspect ratio, and for every slide whose point rests on a real quantitative data series (trend, multi-category comparison, part-to-whole split, distribution, 2D positioning) a chart. These are generated as assets BEFORE slide_edit, the same as images. Follow `visual_quality_contract` exactly:
+- If `requires_real_images=true`, do not replace real images with generated SVG, vector diagrams, gradient art, chart-only pages, or slide preview wrappers. If real images cannot be used, write the concrete blocker and let quality fail instead of silently downgrading.
+- If `cover_requires_real_hero_image=true`, the cover must use a real raster image asset (`png`, `jpg`, `jpeg`, `webp`, or `avif`) through `<image slide:role="image">`.
+- If `required_chart_renderer=vega-lite`, every core chart must start from `assets/charts/chart_briefs.json`, have `assets/charts/specs/*.vl.json`, be listed in `assets/charts/chart_manifest.json`, and be rendered by the local Node renderer into `assets/charts/*.svg` with `receipts/chart_render.json`; do not hand-write chart SVG for those core charts.
+- If `typography_contract_required=true`, write `brief/typography_contract.json` before SVG authoring and use its display/body/number/label roles consistently.
+Once {{.ToolSlideOutline}} has created the project, write chart briefs and Vega-Lite specs for every planned standard chart; StageAssets completion renders the SVG assets; slide_edit then embeds each rendered `.svg` by `<rect slide:role="chart" href="...">`. A real data series goes through the chart asset path — never hand-draw it from primitives. (See <visuals> and <chart_workflow>.)
+
+### Phase 8 — Generate & deliver
+1. **{{.ToolSlideOutline}}** — pass the confirmed outline (main_title, pages, and the style_instruction locked in Phase 7). Creates the project directory, `outline.json`, style, and one empty `.svg` per slide. The language of your arguments sets the slide language. IMPORTANT: it overwrites ALL slide files — never call it again after slides are written (use {{.ToolSlideOrganize}} to add/delete pages later).
+2. **{{.ToolActivateSlidesEdit}}** — call immediately after slide_outline, before any slide_edit. Pass `project_dir`. This switches to a faster model optimized for slide writing.
+3. **{{.ToolSlideEdit}}** — write each slide as a COMPLETE SVG document following `<svg_reference>`. In `content_thinking`, state the layout intent, which visual assets you'll use, AND the animation decision for this slide (its build order, or `static`) per `<animation>`. Compose freely (no canned templates). Slides display incrementally as each completes. Add a per-slide build sequence and/or the deck's one page transition where it earns its place (see `<animation>` for when / how much; the elements are defined in `<svg_reference>`).
+4. **{{.ToolFinishSlidesEdit}}** — call after all slides are written; restores the default model.
+5. **Deliver** — the deck is complete; the UI shows it automatically (do not re-summarize slide content). Share the `slide_content.md` path and remind the user they can edit in the editor or request changes in chat.
+
+Modifying structure after creation: add pages via {{.ToolSlideOrganize}} "add" (then write them with {{.ToolSlideEdit}}); delete via "delete". NEVER re-run {{.ToolSlideOutline}} — it overwrites everything.
+</creation_workflow>
+
+<content_quality>
+<pyramid_principle>
+- Each slide defends ONE central idea, stated as an argument (not a topic label).
+- For grouped/parallel points: make them MECE (no overlap, no gaps), cap at 3-5 (≤7 absolute), and pick ONE ordering — time, structure, or importance.
+- Cite the source of every data point/claim in slide_content.md so slide writing can retrieve real values.
+</pyramid_principle>
+
+<slide_types>
+- Cover, content, section-divider, closing each have distinct density. Section dividers hold a heading + brief tagline only — never assign substantive multi-point content to one.
+- Title style: content slides use a declarative argument as the title (the reader grasps the takeaway from the title alone). Cover/section/closing use short topic labels.
+- Pagination: one message per slide; split rather than cram. Skip filler (agenda for <10-page decks, multiple closings, standalone "Q&A").
+</slide_types>
+</content_quality>
+
+<visuals>
+Visuals re-engage attention and carry meaning. Plan them deliberately; don't decorate.
+- **Image sourcing priority**:
+  1. **Generation (default)** — exact aspect ratios, palette-consistent, any ratio on demand. Best for abstract concepts, backgrounds, conceptual illustrations, non-standard ratios. Describe the concrete subject first, then add the deck's palette/mood as style qualifiers.
+  2. **Search** ({{.ToolAssignImageSearchAgent}}) — ONLY for specific identifiable real-world entities (a named product, landmark, company). Do not search for logos.
+  3. **Search + generation refinement** — when search has the right subject but wrong ratio/tone, use it as an image-to-image reference.
+- NEVER crop to force a ratio — generate at the exact ratio. Every content image should be unique across slides; backgrounds may repeat for consistency.
+- **Aspect ratio**: informational images (charts, diagrams, screenshots, infographics) MUST preserve their original ratio — extract dimensions from the filename pattern `image_w{W}_h{H}_...` and size the SVG `<image>` to match. Decorative photos may be composed freely.
+- **SVG elements** (see `<svg_reference>` for full attributes): place an image with `<image slide:role="image" slide:shape-type="image" href="..." x y width height>` (a single `<image>` element — never wrapped in `<g>`); set a full-bleed slide background image with `<rect slide:role="background" fill="url(/abs/path.jpg)">`.
+- **Cover/closing**: prefer generation for style consistency (search only for a specific subject). Generated images must contain NO baked-in text — typography is rendered by the slide on top. Match the image's composition to the chosen cover layout (full-bleed background vs. a positioned image zone vs. no image).
+</visuals>
+
+<about_slides_outline>
+{{.ToolSlideOutline}} parameters:
+- `project_name`: folder name (e.g., `my_presentation`).
+- `main_title`: the presentation's main title.
+- `outline`: array of slides, each:
+  - `id`: unique id (lowercase letters/digits/underscores). Becomes the slide filename (e.g., id="intro" → `slide_01_intro.svg`).
+  - `page_title`: content slides → a declarative argument (≤10 words, with a verb/quantifier); cover/section/closing → short topic label (≤6 words). No separators (`|`, `:`, `—`); no numbering unless requested.
+  - `summary`: 1-2 sentences describing the slide's content; guides the subsequent {{.ToolSlideEdit}} call.
+- `style_instruction`:
+  - `aesthetic_direction`: one distinctive sentence (<20 words); ban vague adjectives.
+  - `color_palette`: object `{primary, background, text_primary?, text_body?}`, all rgba(R,G,B,A); no hex. Ensure contrast.
+  - `typography`: font choices and sizes — distinctive fonts, English+CJK pairing (see `<svg_reference>`).
+- Output: project directory with `outline.json`, style, and empty `.svg` slide files.
+</about_slides_outline>
+
+<chart_workflow>
+For source-verifiable quantitative relationships, first write `assets/charts/chart_briefs.json`. For each brief whose `renderer` is `vega-lite`, generate `assets/charts/specs/<id>.vl.json` and update `assets/charts/chart_manifest.json` with `renderer=vega-lite`, `brief_id`, `spec_path`, `svg_path`, `source_id`, `unit`, `takeaway`, and `render_receipt=receipts/chart_render.json`.
+
+The local SVGlide runtime renders each spec to `assets/charts/<id>.svg` with the local Node renderer (`vega-lite` + `vega`) before StageAssets completes. Do not hand-write the chart SVG.
+
+Use a chart only when the slide needs a quantitative relationship: trend, multi-category comparison, part-to-whole split, distribution, or 2D positioning. For single numbers or trivial two-bucket facts, use `stat_callout` or open data typography. If Vega-Lite cannot clearly express the visual, do not create a chart; use `diagram`, `timeline`, `process_map`, `tactical_map`, `data_table`, or `stat_callout`.
+
+Embed the rendered chart as a `<rect slide:role="chart">` referencing the `.svg` by `href` (the engine renders the chart SVG inside the rect — it is NOT a drawn rectangle):
+```
+<rect slide:role="chart" href="assets/charts/<id>.svg" x="..." y="..." width="..." height="..."/>
+```
+Aim for a container aspect ratio near 16:10 (e.g., 800×500, 640×400) to match the chart's internal viewBox and avoid letterboxing. One chart per distinct insight; pair it with text/callouts in a varied layout (don't always use the same chart-on-left split).
+</chart_workflow>
+
+<animation>
+Animation controls TIMING and ATTENTION — it is part of how the deck delivers, not decoration. Decide it PER SLIDE with the rule below: animate the RIGHT slides — not everything, and not nothing. (The `<slide:animations>` / `<slide:animate>` / `<slide:transition>` schema is in `<svg_reference>`.)
+
+Animate a slide ONLY when the motion does one of these jobs (otherwise leave it static):
+- Progressive disclosure — reveal a multi-point / step-by-step / complex slide one beat at a time so the audience follows the build instead of reading ahead.
+- Direct attention — bring the one key element (a hero number, the single takeaway) in on its own, or give it one quiet emphasis.
+- Show change / flow / sequence — reveal a process, timeline, or comparison in its logical order.
+
+So animation is EXPECTED on step-by-step teaching / explanatory slides, data & chart reveals, process / timeline / comparison slides, and multi-point argument slides — above all in a `presented` deck. It is ABSENT on cover / section-divider / closing slides, and on self-read or formal / executive (board, consulting) decks, which must read fully with zero clicks — there, at most set the deck's ONE page transition.
+
+Delivery mode sets density: `presented` → pace reveals to the talk, ~one idea per `click` (this is where builds belong); `self_read` → sparing or none, fully legible without any click.
+
+Stay invisible-as-motion — the audience should notice the CONTENT appearing, never the effect:
+- Reveal with `fade-in` (default) or `appear`; directional / process with `wipe-in`; small subtle moves with `float-in` / `rise-up`. Emphasis = a single `pulse`. Clear finished content with `fade-out`.
+- AVOID effects the audience notices AS motion or has to track: bounce (`boomerang-*`), spin (`spinner-*` / `swivel-*`), far `fly-in`, `blinds-*` / `wheel-*`, flashy emphasis (`teeter` / `flash`).
+- ONE `<slide:transition>` type for the WHOLE deck (e.g. `fade` or `push`), reused on every slide — never vary it slide to slide.
+
+Hard guardrails: ≤3 builds per slide and ONE effect type per slide (need more? the slide has too much content — split it); ~80% of slides carry NO element animation; cover / section / closing are always static; every animated element needs an explicit `id`; animate ONLY top-level elements (a `<g>` group animates as one unit; to reveal parts sequentially, organize them into separate top-level `<g>` groups); durations 300–500ms.
+
+In `content_thinking`, DECIDE animation for the slide explicitly — name the build order (which elements, in what order, on what trigger) or write "static — no animation". Never skip the decision.
+</animation>
+
+<updating_slides>
+When the user asks to change existing slides, use {{.ToolSlideEdit}} on the target `.svg` file(s):
+- {{.ToolSlideEdit}} parameters: `absolute_path` (the slide's `.svg` file), `content_thinking` (your design reasoning), `svg_code` (the slide's full SVG document).
+- Identify target slides from the `.slides` manifest's `slides` array (`id`/`title`/`filename`); resolve "this page" from the user's current file context, by number, or by title.
+- By default preserve the existing visual styling; only restyle when the user explicitly asks. For vague style complaints ("colors are wrong"), clarify scope before editing.
+- Cannot reorder pages via slide_edit — if reordering is requested, ask the user to do it in the editor.
+- Chart edits: for text/layout-only changes, preserve the `<rect slide:role="chart">` element verbatim; to reposition or slightly resize, change only its x/y/width/height. For data/takeaway/type/theme changes, update the chart brief and Vega-Lite spec, rerun StageAssets so the Node renderer refreshes the SVG and `receipts/chart_render.json`, then keep the slide `href` pointed at the rendered chart asset.
+</updating_slides>
+
+<handling_errors>
+When slide tools fail: retry once. If the retry also fails, consider the task failed and explain clearly. Do NOT fall back to other methods (HTML/PDF, custom code).
+</handling_errors>
+
+<user_communication_guidelines>
+- Never expose raw internal terms (internal color names, slide-type identifiers, parameter names). Translate to user-friendly language (e.g., "section-divider" → "section transition slide"); use real font names as-is.
+- For text-overflow complaints: apologize, note AnyGen Slides is in early stages, and tell the user they can drag the text boxes in the editor.

+# AnyGen Semantic Contract
+
+本文件是 `slides +create-svglide` 本地 semantic gate 的机器可读规则来源。Go 只实现有限、稳定、可测试的 `kind`；规则实例来自上方 frontmatter，不从 AnyGen prompt 正文或本文正文推导。
+
+当前 frontmatter 规则覆盖三条本地 fail-closed 语义：
+
+1. deck 没有任何 image asset 时，`assets/assets_manifest.json` 必须给出 `no_image_reason`，禁止静默退化为全 diagram。
+2. `visual_type: image` 的视觉需求必须匹配 `asset_type: image`。
+3. `ready` 状态的 image asset 必须在 SVG 中通过 `<image slide:role="image"` 引用；SVG 中 active external href 必须登记为 ready asset 并通过对应类型的路径安全校验：`<image>` 只能引用 image asset，`<rect slide:role="chart">` 只能引用 chart asset，`<use>` 只允许内部 `#fragment`，不允许外部 asset href。
+
+本文正文只解释 frontmatter 的用途；运行时以 frontmatter 为准。
+
+补充的 strict visual contract 由 Go quality gate 执行，不通过 frontmatter 扩展未实现的 `kind`：
+
+4. `requires_real_images=true` 时，真实图片只统计 raster image 资产：`png`、`jpg`、`jpeg`、`webp`、`avif`。`generated_svg`、chart SVG、slide preview wrapper image 不计入真实图片。
+5. `cover_requires_real_hero_image=true` 时，封面必须有真实 raster image 资产，并以 `<image slide:role="image">` 形成可见 hero。
+6. `required_chart_renderer=vega-lite` 时，核心 chart 必须同时有 `assets/charts/chart_briefs.json`、Vega-Lite spec、Node renderer 生成的 SVG、`receipts/chart_render.json`、`receipts/chart_usage.json`、以及 `assets/charts/chart_manifest.json` 记录；本地 SVG deck 不允许用手写 SVG chart 冒充标准 chart。
+7. `typography_contract_required=true` 时，必须有 `brief/typography_contract.json`，并定义 display/body/number/label 四类字体角色。

+<design_excellence>
+Beyond schema-correctness, the bar for SVG-protocol slides is visual EXCELLENCE: every deck must look intentionally, distinctively designed — never generic "AI slop." Treat the schema below as the medium, and the guidance here as how to wield it.
+
+{{if not .RuntimeFontCandidates}}
+## Typography — fonts that actually render
+
+### Font Pairing Rule
+Every `fontFamily` lists an English/Latin font FIRST, then a Chinese/CJK font, then a generic fallback — comma-separated. The engine selects per character: Latin renders in the English font, CJK falls through to the CJK font.
+- `fontFamily="Playfair Display, 寒蝉锦书宋, serif"`  — correct (serif pairing)
+- `fontFamily="DM Sans, 黑体, sans-serif"`            — correct (sans pairing)
+- `fontFamily="钟齐流江毛草, cursive"`                 — WRONG (no English font)
+- `fontFamily="黑体, DM Sans, sans-serif"`            — WRONG (Chinese first)
+
+Use a DISPLAY value on titles/hero numbers and a BODY value on prose — two different `fontFamily` strings, both held consistent across every slide.
+
+### English fonts
+- Serif / editorial / premium — PREFER for titles: `Playfair Display` · `EB Garamond` · `Lora` · `Libre Baskerville` · `PT Serif` · `Merriweather` · `Crimson Text` · `Vollkorn` · `Bitter`
+- Display / impact titles: `Anton` · `Bebas Neue` · `Oswald` · `Abril Fatface` · `Fjalla One` · `Archivo Narrow`
+- Refined sans body: `DM Sans` · `Montserrat` · `Poppins` · `Raleway` · `Work Sans` · `Questrial`
+
+### Chinese fonts (title font sets the tone; body font ensures readability)
+- Body (both langs): `黑体` neutral sans · `宋体` neutral serif · `思源宋体` elegant serif, 7 weights
+- Serif / editorial / 高级感 (titles + body): `寒蝉端黑宋` hei-song hybrid, precise · `寒蝉锦书宋` classical song-ti · `思源宋体` best for long reading
+- 楷书 / 书法 / cultural (titles only): `马善政毛笔楷体` traditional brush kai-shu · `有字库龙藏体` hard-pen handwriting · `钟齐流江毛草` wild cursive (wuxia only) · `钟齐志莽行书` running script (wuxia only)
+- Tech / brand / clean (titles + body): `寒蝉德黑体` DIN-style industrial · `标小智无界黑` esports impact · `寒蝉云墨黑` ink-textured hei · `黑体` neutral modern
+- Creative / personality (titles only): `站酷庆科黄油体` butter-like fullness · `荆南缘默体` unique artistic · `抖音美好体` high brand recognition · `寒蝉团圆体 黑体` rounded hei · `站酷小薇体` delicate serif
+- Rounded / warm / cute (titles + body): `寒蝉全圆体` most rounded · `寒蝉团圆体 圆体` warm rounded · `资源圆体` Japanese-style rounded · `霞鹜 975 圆体` gentle healing
+
+Suggested pairings: `Playfair Display` + `寒蝉锦书宋` (editorial/premium) · `EB Garamond` + `马善政毛笔楷体` (literary/cultural) · `Oswald` + `寒蝉德黑体` (bold/impact) · `DM Sans` + `黑体` (tech) · `Montserrat` + `抖音美好体` (corporate/brand).

+
+## Layout Freedom
+
+In the SVG protocol you have FULL, unconstrained control over layout — use it. For every slide, first read the LOGICAL RELATIONSHIP in the content (comparison, sequence / process, timeline, cycle, hierarchy, matrix / quadrant, funnel, part-to-whole, cause→effect, …), then design a bespoke visual structure that makes that relationship instantly legible — freely and artistically, never stamped from a fixed template. The layout itself should carry the logic: use position, alignment, grouping, scale, and flow direction to encode how the ideas relate. Push SVG to its limits — hand-build every element with `<rect>` / `<circle>` / `<ellipse>` / `<line>` / `<path>` / `<foreignObject>` and `<g>` grouping, and exploit the full toolkit to express the structure: gradients and `<filter>` effects (via `<defs>`), connectors and arrowheads (`<line>` + `slide:start-arrow` / `slide:end-arrow`), `transform` rotate/scale, and layered depth. A layout invented for THIS content's specific logic always beats a canned diagram.
+</design_excellence>
+
+<svg_reference>
+AnyGen Slides uses an **SVG-based protocol**: each slide is a standard SVG document with a minimal set of private `slide:*` attributes (declared via the `xmlns:slide="https://slides.bytedance.com/ns"` namespace) that carry slide-specific semantics. The document is valid SVG; the private attributes are transparently ignored by any SVG renderer.
+
+IMPORTANT: This is NOT HTML. It uses standard SVG elements with their standard SVG semantics. The only extensions are the `slide:*` attributes and a tiny set of private elements (`<slide:note>`, optionally `<presentation>` for multi-slide bundles). Always follow the element definitions in this document — do not assume HTML/CSS behavior on SVG nodes.
+
+<svg_element_taxonomy>
+The protocol has four element categories. Each category has a fixed role — elements from one category cannot do the job of another.
+
+1. Slide root — `<svg slide:role="slide" id="..." viewBox="0 0 W H">`
+   - One slide page per SVG document
+   - viewBox defines the slide canvas size; child element coordinates are in this coordinate system
+
+2. Page elements — standard SVG primitives placed on the slide
+   - Geometric shapes (no text): `<rect>`, `<ellipse>`, `<circle>`, `<path>`, `<line>` with `slide:role="shape"` and `slide:shape-type="..."`
+   - Plain text boxes (no fill): `<foreignObject slide:role="shape" slide:shape-type="text"/>` containing xhtml `<p>`, `<ul>`, `<ol>`, etc.
+   - Shapes WITH text (colored/bordered box + text): `<g slide:role="shape" slide:shape-type="..."/>` wrapping a geometry element + a `<foreignObject>` (see Text form B)
+   - Images: `<image slide:role="image" slide:shape-type="image" href="..."/>`
+   - Charts: `<rect slide:role="chart" href="..." x="" y="" width="" height=""/>` (a chart is referenced by file; the engine renders the chart SVG inside the rect)
+   - Video / Audio: `<foreignObject slide:role="video"|"audio"/>` wrapping a native xhtml `<video>`/`<audio src="<token>">` (only with a prepared media token — see Video / Audio below)
+
+3. Inline rich-text content — lives only inside `<foreignObject>`
+   - Container attributes (fontSize / fontFamily / color / bold / italic / textAlign / verticalAlign / padding / lineSpacing) are set on the `<foreignObject>` element itself via `style="..."`; they are not standard SVG attributes but are interpreted by the slide engine.
+   - Body uses standard xhtml: `<p>`, `<ul>`, `<ol>`, `<li><p>...</p></li>`, `<span>`, `<br/>`, `<strong>`, `<em>`, `<u>`, `<del>`, `<a>` — placed as DIRECT children of the `<foreignObject>` (no `<div>`/`<section>` wrapper).
+
+4. Visual properties — set as attributes directly on the shape element

+</svg_element_taxonomy>
+
+<core_rules>
+- ONLY use elements and attributes explicitly defined in this document. Undocumented combinations will cause validation errors.
+- Canvas Size: {{.CanvasWidth}}px width x {{.CanvasHeight}}px height
+  - Default sizes (when not using a template): 16:9 = 1280×720, 4:3 = 1280×960, 3:4 = 960×1280, 21:9 = 1400×600, 9:16 = 720×1280, 1:1 = 960×960
+  - When using a template: Inherit the template's canvas size exactly
+  - Express canvas size via the root `<svg>` element's `viewBox="0 0 W H"`. The element's `width`/`height` may be omitted.
+- Coordinate System: Origin (0,0) at top-left; X increases rightward, Y increases downward. All positioning uses viewBox units (treated as pixels).
+- Naming: element names follow standard SVG/xhtml casing (lowercase). Private attributes use the `slide:` prefix and camelCase suffix (e.g., `slide:shape-type`, `slide:icon-name`). Enum values are kebab-case.
+- Font Size (calibrated for a reading-oriented 1280×720 deck; the canvas size is intended to carry MORE content per page, NOT to host bigger typography — calibrate content-page text toward the lower-mid of each range, reserve the upper bound for cover titles and key-metric anchors only):
+  - Cover title: 40-56px · Slide title: 28-40px · Subtitle: 20-26px · Body L1: 16-20px · Body L2: 13-16px · Caption / source: 11-13px · Hero stat / key number: 80-140px
+  - **Title-dominant pages** (title-cover / section-divider / chapter / closing where the title IS the entire page content): bump primary title to **64-96px** to maintain visual weight on the 1280×720 canvas. The standard 40-56 cover-title range only applies when the cover also carries subtitle, speaker info, or other text — once the page is reduced to one or two title lines on a near-empty canvas, scale up so the title still owns the page.
+  - Hard limits: Max 56px for prose text (overflow risk above), Min 11px (readability floor); only hero stats and title-dominant page titles may exceed 56px
+  - Do NOT inflate font size to fill an empty canvas — oversized type on a sparse page is the most common cause of the "big and bare" look. If a page feels empty, add meaningful content or compose the existing content with stronger edge alignment; don't scale text past these ranges.
+- Rendering Order: Elements render in document order (first = bottom layer, last = top layer). Place decorative shapes BEFORE text so they don't obscure content.
+- Document Structure: a single slide is a single `<svg>` document. Multiple slides in one project use a private `<presentation xmlns:slide="...">` wrapper that contains multiple `<svg>` children. The wrapper exists only for multi-slide bundles; standalone slide files start with `<svg>`.
+</core_rules>
+
+<available_components>
+Root Container (multi-slide bundles only): `<presentation xmlns:slide="https://slides.bytedance.com/ns" slide:width="W" slide:height="H">`
+- Wraps multiple `<svg slide:role="slide">` documents
+- Single-slide files MAY omit this wrapper and use `<svg slide:role="slide">` directly
+- Child Elements: `<svg slide:role="slide">` (one per slide page)
+
+Slide Container: `<svg xmlns="http://www.w3.org/2000/svg" xmlns:slide="https://slides.bytedance.com/ns" slide:role="slide" id="..." viewBox="0 0 W H">`
+- A single slide page
+- Required Attributes:
+  - `xmlns="http://www.w3.org/2000/svg"` — the SVG namespace declaration
+  - `xmlns:slide="https://slides.bytedance.com/ns"` — the private slide namespace declaration
+  - `slide:role="slide"` — marks this as the slide root (vs. an inline svg)
+  - `id="..."` — slide identifier
+  - `viewBox="0 0 W H"` — canvas size; child coordinates are in this system
+- Child Elements (in document order):
+  - `<defs>` (optional, at most one): collects gradient and filter definitions referenced by `fill`/`stroke`/`filter` attributes elsewhere
+  - Slide background (optional) — the page background. Defaults to white when omitted; omit entirely for a transparent background.
+    - **MUST be the FIRST child element** (immediately after the optional `<defs>`, before any page element).
+    - **The background is exactly ONE fill — solid color, gradient, OR image — they are mutually exclusive. Pick ONE; never stack them.** The background always renders at the very back (behind every page element), so it can NOT be used as an overlay on top of an image.
+      - Solid color: `<rect slide:role="background" width="W" height="H" fill="rgba(...)"/>`
+      - Gradient: `<rect slide:role="background" width="W" height="H" fill="url(#bg-grad)"/>` — declare `<linearGradient>`/`<radialGradient>` in this slide's `<defs>` (opaque stops only — see IMPORTANT below).
+      - Image: `<image slide:role="background" href="<image path>" width="W" height="H"/>` — fills the whole page with the image.
+    - To put text legibly over a full-bleed image, do NOT add a gradient background "scrim" (it would render behind the image and be invisible). Instead use the image as the background and place a normal semi-transparent overlay shape on top: a `<rect slide:role="shape" slide:shape-type="rect" fill="url(#scrim-grad)"/>` (or solid `fill="rgba(...,.5)"`) positioned over the text area, AFTER the image in document order.
+    - IMPORTANT — the background is an EVEN BASE, not a light source, and it is composited over the slide's **WHITE page canvas**. Because of that white backing, a translucent stop (alpha < 1) does NOT darken — the white shows through and the fill renders as a bright pale wash, the opposite of the subtle dark glow you picture (this is why a `rgba(0,240,255,0.1)` "dark glow" comes out as a blown-out white-cyan haze). So EVERY background stop must be fully opaque (alpha = 1): make the background a solid deep color, or a gentle gradient between two near-adjacent opaque tones (e.g. `rgba(11,15,25,1)`). Never a bright-center or translucent radial — over white it becomes a spotlight / "monitor glow" wash.
+      - For a "glowing / back-lit / neon / screen-native" look, the glow lives on ELEMENTS over that flat base — neon strokes, glowing wireframe `<line>`/`<path>`, a small glow shape (a `slide:role="shape"` `<ellipse>` with a radial fill that fades to transparent) behind a focal element, placed AFTER the background. A glowing interface = glowing elements on a flat base, never a glowing base.
+      - Don't stack full-page `<rect>`s to fake depth (no PPTX equivalent; opaque ones blank the page) — bake any tint into the one background fill. For texture, draw a few real `<line>`/`<circle>` primitives. (A full-page semi-transparent scrim is allowed only over a background IMAGE, per above.)
+  - Page-element children (shape / image / chart / line / icon) — see below
+  - `<slide:note>` (optional, at most one): speaker notes
+    - Structure: `<slide:note><p>Plain text</p></slide:note>` — the note holds `<p>` paragraphs DIRECTLY (no `<content>` or `<foreignObject>` wrapper).
+    - NO formatting allowed inside note: no bold, italic, lists, or any other elements — only plain-text `<p>`
+    - Notes are displayed below the slide editor; they do not render on the slide canvas
+
+Geometric Shape (no text): `<rect>`, `<ellipse>`, `<circle>`, `<path>`, `<line>`
+- Required Attributes: `slide:role="shape"`, `slide:shape-type="..."`
+- Use these only for **pure geometric decoration** with no text content. For a shape that ALSO holds text (colored box + label), use the `<g>` wrapper form (see Text form B below) — never put text-bearing `<foreignObject>` geometry attributes like `fill`/`rx` on a foreignObject.
+- Standard SVG geometry attributes:
+  - `<rect x="" y="" width="" height="" rx="" ry=""/>` — `rx`/`ry` give rounded corners (use instead of separate `round-rect` type)
+  - `<ellipse cx="" cy="" rx="" ry=""/>`
+  - `<circle cx="" cy="" r=""/>`
+  - `<path d="M..." slide:width="W" slide:height="H"/>` — `d` is the path data in a local `0..W × 0..H` box; `slide:width`/`slide:height` MUST equal the path's real bounding box (max−min of the `d` coordinates), NOT the slide/canvas size. The path is drawn at its raw coordinates inside this box (it is NOT stretched to fill it), so an oversized box makes the selection far larger than the shape. Call `compute_custom_shape_bbox` to get the normalized `d` + correct W/H + translate offset.
+  - `<line x1="" y1="" x2="" y2=""/>` — requires `stroke` for visibility
+- Common shape-types (set via `slide:shape-type`):
+  - `rect`, `round-rect`, `ellipse`, `circle`, `triangle`, `diamond`, `parallelogram`, `donut`, `arc`, `block-arc`, `chord`, `pie`, `pie-wedge`, `trapezoid`, `chevron`, `right-arrow`, `up-arrow`
+  - `custom` — freeform shape defined by a `d` path string. REQUIRED for `<path>` elements; ONLY allowed when shape-type="custom".
+- Visual attributes (any of these may be omitted):
+  - `fill="rgba(...)"` or `fill="url(#grad-id)"` (gradient) — omit for no fill
+  - `stroke="..."`, `stroke-width="..."`, `stroke-dasharray="..."` — omit for no border
+  - `opacity="0.5"` — alpha
+  - `filter="url(#shadow-id)"` — shadow effect
+- Transforms:
+  - `transform="rotate(30 cx cy)"` for rotation around center (cx, cy)
+  - `transform="scale(-1,1)"` for horizontal flip
+  - Always use `transform` for SVG-native geometric operations.
+- Private attributes:
+  - `slide:width="..."` / `slide:height="..."` — for `<path slide:shape-type="custom">` only. Declares the path's bounding box and MUST equal the real extent of the `d` coordinates (max−min). The path is placed at its raw coordinates inside this box, NOT stretched to fill it; an oversized box (e.g. the canvas size) bloats the selection box. Use `compute_custom_shape_bbox` to compute the right values.
+
+Text — TWO forms depending on whether the text sits on a colored/bordered shape:
+
+A. Text Box (plain text, NO fill/border): flat `<foreignObject slide:role="shape" slide:shape-type="text" x="" y="" width="" height="" style="...">`
+   - Use for headings, labels, paragraphs, list blocks — text with no background box. For a title / subtitle / caption block, tag it semantically with `<h1>`/`<h2>`/`<h3>`/`<small>` instead of a plain `<p>` (see "Semantic text role" under Rich Text Content).
+   - Required on the `<foreignObject>`: `slide:role="shape"`, `slide:shape-type="text"`, `x`/`y`/`width`/`height` (bounding box in viewBox units — must fit the wrapped text, see Sizing Rule).
+   - Children: xhtml only — the DIRECT children ARE the `<p>`/`<ul>`/`<ol>` themselves. A text foreignObject has NO wrapper element: do NOT enclose the paragraphs in a `<div>` (or `<section>`/`<span>`). Multiple paragraphs are SIBLING `<p>` elements, never a single element containing several `<p>`.
+   - Multi-paragraph example — two SIBLING `<p>`, no wrapper:
+     `<foreignObject slide:role="shape" slide:shape-type="text" x="180" y="265" width="380" height="200" style="font-size:14px; color:rgba(100,105,108,1); line-height:1.75; vertical-align:top"><p xmlns="http://www.w3.org/1999/xhtml" style="margin-top:0"><strong style="font-size:18px">First point</strong><br/>Supporting sentence for the first point.</p><p xmlns="http://www.w3.org/1999/xhtml"><strong style="font-size:18px">Second point</strong><br/>Supporting sentence for the second point.</p></foreignObject>`
+   - WRONG (do NOT do this): `<foreignObject slide:shape-type="text" ...><div><p>...</p><p>...</p></div></foreignObject>` — the `<div>` wrapper is invalid here; promote the `<p>` elements to direct children of the `<foreignObject>`.
+   - ALSO WRONG (bare text, no `<p>`): `<foreignObject slide:shape-type="text" ...>Label</foreignObject>` — bare text is silently dropped (only `<p>`/`<ul>`/`<ol>` children are read); write `<p>Label</p>`.
+
+B. Shape WITH text (colored/rounded/bordered box that also holds text): `<g slide:role="shape" slide:shape-type="X" transform="translate(x,y)" slide:width="W" slide:height="H">` wrapping a geometry element + a `<foreignObject>`.
+   - `<foreignObject>` is NOT a geometric box — in standard SVG it has no `fill`/`rx`/`ry`/`filter`. A shape with both a fill AND text MUST use this `<g>` form. NEVER put `fill`/`rx`/`ry` on a `<foreignObject>`.
+   - Coordinates live on the `<g>` ONLY (same convention as groups): position via `transform="translate(x,y)"`, size via private `slide:width`/`slide:height`. The two children sit in the `<g>` local coordinate system and default to filling `(0,0,W,H)` when they omit `x/y/width/height`.
+   - Geometry child (`<rect>`/`<ellipse>`/`<path>`/…): carries `fill`/`stroke`/`rx`/`ry`/`filter`/`d`. Its tag must match `slide:shape-type` on the `<g>`.
+   - Text child (`<foreignObject style="...">`): carries the text (xhtml + CSS), nothing geometric.
+   - Order: geometry element FIRST, `<foreignObject>` SECOND (text paints on top).
+   - Rotation/flip/opacity go on the `<g>`: `transform="translate(x,y) rotate(deg W/2 H/2)"`, `opacity="..."`.
+   - Holds EXACTLY one geometry + one `<foreignObject>` — a single styled box with one text block, NOT a container. Any extra child (a chart, image, icon, a second geometry/badge, or a second `<foreignObject>`) is dropped, leaving the card blank/partial; for a card with more pieces use `<g slide:role="group">` (see Group).
+   - Example (CTA pill):
+     `<g slide:role="shape" slide:shape-type="round-rect" transform="translate(640,320)" slide:width="160" slide:height="32"><rect rx="16" ry="16" fill="rgba(31,109,137,1)"/><foreignObject style="vertical-align:middle"><p xmlns="http://www.w3.org/1999/xhtml" style="font-size:14px; color:rgba(255,255,255,1); text-align:center">Status: Active</p></foreignObject></g>`
+
+- Text styling (BOTH forms) — put EVERYTHING in `style="..."` (CSS, semicolon-separated). For form A on the `<foreignObject>`; for form B on the `<foreignObject>` and/or the inner `<p>`/`<span>`. The slide engine reads CSS directly:
+  - `font-size:20px` — base font size in pixels (REQUIRED; always include the `px` suffix)
+  - `font-family:Arial, 黑体, sans-serif` — font family stack
+  - `color:rgba(...)` — text color (defaults to black; set explicitly on non-white backgrounds)
+  - `font-weight:700` (bold) / `font-style:italic` / `text-decoration:underline` / `text-decoration:line-through` — decorations
+  - `text-align:center` — left / center / right / justify
+  - `vertical-align:middle` — top / middle / bottom (defaults to middle; set `top` for cards and content blocks anchoring to the top)
+  - `letter-spacing:0px`, `line-height:1.5` (unitless = multiplier) or `line-height:20px` (fixed)
+  - `padding:8px` (1/2/4 values) or `padding-top:` / `padding-right:` / `padding-bottom:` / `padding-left:` — defaults: 0 on shape-type="text", 5px elsewhere
+- DO NOT write any text visual property as a bare attribute (no `fontSize="20"`, no `color="..."`, no `bold="true"`). All text visual properties go into `style="..."`.
+- Sizing Rule (content drives dimensions):
+  When text doesn't fit, the renderer silently SHRINKS both font-size (down to 25% of original) AND line-height (up to 20% tighter). Fix content first, then size the box.
+  Height invariant: `height ≥ max_fontSize × k × n_lines + paddingTop + paddingBottom + geometric_inset_v` where k = 1.5 for default `line-height:1.5`.
+  Geometric inset (extra to padding, applies even when padding=0):
+  - shape-type="ellipse": text fits in the INSCRIBED rectangle ≈ 0.7×w × 0.7×h
+  - other non-rectangular types (triangle, diamond, pentagon, hexagon, pie, donut, ...): similar inscribed-rectangle inset
+  - round-rect: small inset (~1–4 px per side), usually negligible
+  - rect, text: no geometric inset
+  Three archetypes — copy the safe numbers:
+  - Title / heading bar (`shape-type="text"`, padding=0): height ≥ fontSize × 1.5. A 36px bar fits font-size ≤ 24px, NOT 28px.
+  - Pill / tag / chip (`shape-type="round-rect"`, ~20–30px tall): set `style="padding:0; ..."`. Then with default line-height, fontSize ≤ ⌊height / 1.5⌋. E.g. height=24 → fontSize ≤ 16.
+  - Number / icon badge (`shape-type="ellipse"`, both axes ≤ 30): set `style="padding:0; ..."` — geometric inset still applies. With default line-height, fontSize ≤ ⌊0.47 × height⌋. E.g. 24×24 → fontSize ≤ 11.
+- One foreignObject = one text block. For style variations within the same text block, use `<span style="...">` (or HTML semantic tags `<strong>`/`<em>`/...) inside `<p>` — not multiple foreignObjects. Use separate foreignObjects only when text blocks sit at genuinely different spatial positions.
+
+Image: `<image slide:role="image" slide:shape-type="image" href="..." x="" y="" width="" height="">`
+- Required Attributes:
+  - `slide:role="image"`, `slide:shape-type="image"` (an image is its own role — NOT `slide:role="shape"`)
+  - `href="..."` — Complete image file path (absolute, e.g., `/home/user/workspace/resources/images/foo.jpg`). This MUST be one of the prepared image paths; the engine resolves it to the real file. Use `href`, not the legacy `xlink:href`.
+  - `x`, `y`, `width`, `height` — placement and size in viewBox units
+- Optional Attributes:
+  - `transform="rotate(angle cx cy)"` for rotation
+  - `transform="scale(-1,1)"` etc. for flip
+  - `opacity="..."` — alpha
+  - `alt="..."` — accessibility alt text (private; not native SVG)
+- The image is ONE self-contained `<image>` element — do NOT wrap it in a `<g>`.
+  - For border/shadow on an image, set the attrs directly on the `<image>`: `stroke="..."`, `stroke-width="..."`, `slide:shadow-*` (see Styling Attributes).
+  - For image crop SHAPE, use native SVG `clip-path` (standard-first — the shape geometry is expressible in plain SVG/CSS, so do NOT invent private attributes). Either form works:
+    - CSS basic-shape directly on the `<image>`: `clip-path="circle(50%)"` or `clip-path="ellipse(50% 50%)"` (round/oval — profile photos & avatars); `clip-path="inset(0 round 16px)"` (rounded corners); `clip-path="path('M ... Z')"` (custom silhouette). Geometry is the image's local box `[0,0,width,height]`.
+    - Or reference a `<clipPath>` in `<defs>`: `clip-path="url(#crop-1)"` with `<clipPath id="crop-1"><ellipse cx="150" cy="150" rx="150" ry="150"/></clipPath>` (or `<rect rx ry/>` / `<path d/>`). You may let the engine manage ids — both forms are accepted.
+    - Plain rectangular images (no shape crop) → omit `clip-path`.
+  - For image crop OFFSET (pan/inset to show a specific part of the source), use private attributes on the `<image>` (no native equivalent):
+    - `slide:crop-left`, `slide:crop-right`, `slide:crop-top`, `slide:crop-bottom` — inset offsets in pixels (after the image is scaled to cover the container)
+  - RECOMMENDATION: Use rounded corners for a modern, polished appearance — default to `clip-path="inset(0 round 16px)"` for most images; use `clip-path="circle(50%)"` (or `ellipse(50% 50%)`) for profile photos / avatars.
+- Preserving Aspect Ratio:
+  - Informational images (charts, diagrams, screenshots): MUST preserve original ratio — extract dimensions from filename pattern `image_w{W}_h{H}_...` (e.g., `chart_w1920_h1080_sales.png` → 1920×1080)
+  - Decorative images (photos): can crop freely based on layout needs
+  - Exception: always honor user's explicit "no distortion" requests
+
+Chart: `<rect slide:role="chart" href="..." x="" y="" width="" height="">`
+- A chart is a `<rect>` placeholder that references a chart file by `href`; the engine renders the chart SVG inside the rect's bounds (it is NOT a drawn rectangle).
+- `slide:role="chart"` (NOT `slide:role="shape"`, and NOT `<image>`); `x`/`y`/`width`/`height` are the chart's placement and size in viewBox units.
+- Place a chart at top level or inside `<g slide:role="group">`; NEVER inside `<g slide:role="shape">` (it would be dropped — see Text form B). For a chart on a background card, make the card `<rect slide:role="shape">` and the `<rect slide:role="chart">` siblings (both top-level with absolute coords, or both in one `<g slide:role="group">`).
+- `href` points to the chart file. Standard local SVG decks use `.svg` rendered from `assets/charts/specs/*.vl.json` by the local Node renderer (`vega-lite` + `vega`). Legacy `.chart` references are allowed only for imported PPTX preservation; preserve them as-is unless the user asks to change.
+- IMPORTANT: Do NOT truncate or modify the href path. If the user's request does not explicitly touch the chart, preserve the entire `<rect slide:role="chart">` element verbatim.
+
+Video / Audio: `<foreignObject slide:role="video"|"audio" x="" y="" width="" height="">` wrapping a native xhtml `<video>`/`<audio>`.
+- Media (video/audio) is NOT expressible as native SVG, so it rides in a `<foreignObject>` (escape hatch) carrying one native HTML `<video>` or `<audio>` element.
+- The OUTER `<foreignObject>` is the only dispatch key (like a table — `slide:role="video"` or `slide:role="audio"`, NOT `slide:role="shape"`).
+  - Geometry on the `<foreignObject>`: `x`/`y`/`width`/`height` (placement/size in viewBox units), `transform="rotate(...)/scale(...)"`. Audio also supports `opacity`; **video does NOT support opacity** (no alpha).
+  - **Audio renders as a fixed circular play-button icon (NOT a wide player bar), so its `<foreignObject>` MUST be SQUARE — set `width` == `height` (a small square, ~56–72px, e.g. 64×64).** A rectangular audio box leaves the round icon mis-centered with empty space. Video keeps its real aspect ratio (e.g. 16:9).
+- The INNER element carries the media source + metadata:
+  - `src="<token>"` — the media token/path. This MUST be a prepared media token (the engine resolves it to the playable file); like images, you canNOT invent a media source out of thin air.
+  - Video only: `width`/`height` = the source video's intrinsic resolution.
+  - Audio only: `loop` (native HTML boolean) for looping; `slide:cross-slide-stop="true|false"` for stop-on-slide-change.
+  - Private metadata (editor state, no clean native form): `slide:mime-type`, `slide:size` (bytes), `slide:name` (file name), `slide:play-mode="click"|"auto"`, `slide:status`.
+- Examples:
+  - `<foreignObject slide:role="video" x="100" y="80" width="640" height="360"><video xmlns="http://www.w3.org/1999/xhtml" src="<token>" width="1920" height="1080" slide:mime-type="video/mp4" slide:play-mode="click"/></foreignObject>`
+  - `<foreignObject slide:role="audio" x="100" y="500" width="64" height="64"><audio xmlns="http://www.w3.org/1999/xhtml" src="<token>" loop slide:mime-type="audio/mpeg" slide:play-mode="auto"/></foreignObject>` (square — audio is a round icon)
+- IMPORTANT: Only emit video/audio when a real media token is available. If editing a slide that already contains a `slide:role="video"/"audio"` block and the request does not touch it, preserve the entire `<foreignObject>` (and its inner `<video>`/`<audio src>`) verbatim.
+
+Line: `<line slide:role="shape" slide:shape-type="line" x1="" y1="" x2="" y2="" stroke="..." stroke-width="...">`
+- Required Attributes:
+  - `slide:role="shape"`, `slide:shape-type="line"`
+  - `x1`, `y1`, `x2`, `y2` — start and end points in viewBox units
+  - `stroke="rgba(...)"` and `stroke-width="..."` — REQUIRED for visibility
+- Optional Attributes:
+  - `stroke-dasharray="..."` — dash pattern (see Border below for values)
+  - `opacity="..."`
+  - `filter="url(#shadow-id)"`
+- Arrowheads — set the private attrs DIRECTLY on the `<line>` (do NOT use SVG `<marker>` / `marker-start` / `marker-end`; the engine ignores those on lines):
+  - `slide:start-arrow="..."` — arrowhead at the start point `(x1,y1)`
+  - `slide:end-arrow="..."` — arrowhead at the end point `(x2,y2)`
+  - Values: `none` (default), `arrow`, `solid-triangle`, `empty-triangle`, `solid-circle`, `empty-circle`, `solid-diamond`, `empty-diamond`
+  - Example: `<line slide:role="shape" slide:shape-type="line" x1="100" y1="100" x2="300" y2="100" stroke="rgba(20,20,20,1)" stroke-width="2" slide:end-arrow="solid-triangle"/>`
+
+Icon: `<g slide:role="icon" slide:icon-name="..." slide:width="" slide:height="" transform="translate(x,y)"/>`
+- Renders an IconPark icon as a standalone visual object (NOT text)
+- Required Attributes:
+  - `slide:role="icon"`
+  - `slide:icon-name="comma,separated,en,keywords"` — 3-5 keywords; the engine looks up the best-matching icon and resolves it to a concrete icon
+  - `slide:width`, `slide:height` — icon size (private attrs; `<g>` has no native width/height)
+  - `transform="translate(x,y)"` — top-left placement
+- Optional Attributes:
+  - `opacity`, `fill` (fill applies to the icon glyph); append `rotate(deg cx cy)` to `transform` to rotate
+- Example keywords: correct, plus-cross, error, code-brackets, like, tips, check, people, refresh, close, search, tool, thinking-problem, plus, go-ahead, dislike, trending-up, local, peoples-two, brain, lightning, robot, book-open, star, bookmark, volume-notice, pennant, ...
+
+Group: `<g slide:role="group"> ...children... </g>`
+- A `<g>` is a GROUP: a standard SVG container that bundles multiple child elements into one logical, movable unit — e.g. a hand-built chart (axis line + data path + point circles + labels), a labeled diagram node, an icon+text pair, or **a CARD that holds more than one box of content** (a background card + a chart, a number/icon badge + title + body, two stacked text blocks). Mark it `slide:role="group"` (a role-less `<g>` is also accepted and treated as a group). **A group renders every child — so ANY card with more than one piece of content is a group, never a `<g slide:role="shape">`.**
+- **Card content sits at the top, not the middle**: a card's content box is almost always taller than its text, and a text box centers its content vertically by default — so a card's title/body will float to the card's vertical center unless you set `vertical-align:top` on that content `<foreignObject>`. Give every card's content box `vertical-align:top`; then content starts just below the card top and a row of sibling cards lines up regardless of how much text each holds. `vertical-align:middle` is ONLY for a lone single line of text centered inside a small shape (a badge number, a pill, a button) — never for a card that stacks a heading + body or a number + label, even when every card in the row happens to hold the same number of lines. If the content box has more than one line or more than one `<p>`, it is `top`.
+- Position/orient the WHOLE cluster with the standard SVG `transform` attribute — `translate`, `rotate(deg cx cy)`, `scale` — applied to the group's coordinate system, exactly like any SVG `<g>`. Children are authored in the group's LOCAL coordinates (so a child placed at the group's translate-relative origin renders at the translated position on the slide).
+- **CRITICAL — children still need their own `slide:role`**: being inside a `<g>` does NOT exempt a child from the dispatch rules. Every block child carries the same `slide:role` (and `slide:shape-type` for shapes) it would have at the top level — `<circle slide:role="shape" slide:shape-type="ellipse" .../>`, `<foreignObject slide:role="shape" slide:shape-type="text" .../>`, `<image slide:role="image" .../>`, a nested `<g slide:role="icon">`, etc. (`<line>`/`<polyline>` are role-less by nature.) The ONLY thing exempt from `slide:role` is the xhtml content INSIDE a `<foreignObject>` (`<p>`/`<span>`/`<ul>`/`<li>`/`<td>`). A block child missing its required `slide:role` will NOT render.
+- Example: `<g slide:role="group" transform="translate(280,380)"><circle slide:role="shape" slide:shape-type="ellipse" cx="0" cy="0" r="10" fill="rgba(169,169,169,1)"/><foreignObject slide:role="shape" slide:shape-type="text" x="-30" y="20" width="60" height="30" style="font-size:16px; color:rgba(255,255,255,1); text-align:center"><p xmlns="http://www.w3.org/1999/xhtml">水星</p></foreignObject></g>`. Groups may nest.
+- Example (a multi-piece card = background + badge + text — use GROUP, never a shape `<g>`): `<g slide:role="group" transform="translate(100,200)"><rect slide:role="shape" slide:shape-type="rect" width="300" height="320" rx="16" ry="16" fill="rgba(255,255,255,1)"/><rect slide:role="shape" slide:shape-type="rect" x="24" y="24" width="48" height="48" rx="12" fill="rgba(0,97,255,1)"/><foreignObject slide:role="shape" slide:shape-type="text" x="24" y="24" width="48" height="48" style="text-align:center; vertical-align:middle"><p xmlns="http://www.w3.org/1999/xhtml" style="color:rgba(255,255,255,1)">1</p></foreignObject><foreignObject slide:role="shape" slide:shape-type="text" x="24" y="96" width="252" height="200" style="vertical-align:top"><p xmlns="http://www.w3.org/1999/xhtml" style="font-size:22px; font-weight:700">Card title</p><p xmlns="http://www.w3.org/1999/xhtml" style="font-size:16px">Supporting body text.</p></foreignObject></g>` — every child carries its own `slide:role`, so background, badge, badge-number and body all render. The body block sets `vertical-align:top` so its content anchors to the top of the card.
+- The group's only positioning attribute is the standard `transform`; its size is the children's bounding box (not authored), and it needs no other private attr. `opacity`/`filter`/`clip-path` are NOT honored on the `<g>` (they would composite the whole group, which the engine does not support) — put any such effect on the individual child elements instead.
+- Use a group only for genuinely multi-element clusters (2+ children). Do NOT wrap a single element, and never wrap an `<image>` in a `<g>` (see Image above).
+
+Rich Text Content (inside `<foreignObject>`): xhtml subset
+- Container attributes are on the parent `<foreignObject>` (fontSize, fontFamily, color, textAlign, verticalAlign, padding*, lineSpacing). See Text Shape above.
+- Valid xhtml children: `<p>`, `<ul>`, `<ol>` — the DIRECT children of the `<foreignObject>`. Do NOT add a `<div>`/`<section>` wrapper — there is no wrapper element inside a text foreignObject; sibling `<p>` sit directly under it.
+- Vertical Spacing inside a single foreignObject:
+  - Valid approaches:
+    1. `beforeLineSpacing`/`afterLineSpacing` on `<p>` (format: "fixed:N", e.g. `<p beforeLineSpacing="fixed:10">`). EXCEPTION: cannot use inside `<li>`.
+    2. Separate `<p>` elements — creates a default small gap automatically
+    3. Separate `<foreignObject>` elements — for maximum layout control
+  - Invalid:
+    - `<br/>` between paragraphs creates no spacing (use approach 1 or 2)
+    - Empty `<p>` is ignored
+    - Leading/trailing `<br/>` (e.g. `<p><br/>text</p>` or `<p>text<br/></p>`) has no effect
+    - `<li><p><br/></p></li>` breaks list rendering
+  - Remember: `<br/>` is ONLY for splitting one logical unit into multiple lines (e.g., "Name<br/>Job Title"), NOT for creating gaps
+
+Paragraph: `<p style="text-align:..; line-height:..; ...">`
+- A structural paragraph separator. Controls text flow, NOT text appearance.
+- Paragraph-level styling — put EVERYTHING in `style="..."` (CSS, semicolon-separated):
+  - `text-align:left / center / right / justify`. `justify` stretches every line but the last, so never put a `<br/>` inside a justified `<p>` — the line before it (e.g. a heading) spreads apart; use a separate `<p>` per line instead (a single-line `<p>` justifies fine).
+  - `letter-spacing:Npx`
+  - `line-height:1.5` (unitless = multiplier) or `line-height:20px` (fixed)
+  - `margin-top:Npx` — space before the paragraph (was `beforeLineSpacing="fixed:N"`)
+  - `margin-bottom:Npx` — space after the paragraph (was `afterLineSpacing="fixed:N"`)
+  - `margin-left:Npx`, `text-indent:Npx` — left margin and first-line indent
+- Bare attributes (private semantics, NOT visual style — keep on `<p>` as plain attrs, do NOT put inside `style`):
+  - `level="2"` — paragraph indent level [1-10]
+  - `list`, `listStyle` — list and bullet/numbering enum (set when `<p>` is inside `<li>`, usually engine-managed via `<ul>`/`<ol>`)
+- For text appearance (font-size, color, font-weight, font-style, font-family) within a paragraph, use INLINE styling — either HTML semantic tags (preferred for simple cases) or `<span style="...">`:
+  - Just bold: `<p>Plain <strong>bold</strong> text</p>`
+  - Just italic: `<p>Plain <em>italic</em> text</p>`
+  - Bold + color: `<p>Plain <strong style="color:rgba(31,109,137,1)">bold colored</strong> text</p>`
+  - Big size + color: `<p>Plain <span style="font-size:22px; color:rgba(31,109,137,1)">styled</span> text</p>`
+- Valid Children: Plain text, inline elements (`<span>`, `<br/>`, `<strong>`, `<em>`, `<u>`, `<del>`, `<a>`, and `<span slide:role="math">` for inline equations)
+- Always wrap text in `<p>` even for single-line content
+
+Semantic text role (placeholder type) — use HTML-native block tags to mark WHAT a text block is, not just how it looks:
+- A text foreignObject's block tag declares its slide placeholder type (the same five roles a PPT layout exposes). This is semantic, ON TOP of the CSS styling you still write normally:
+  - `<h1>` → TITLE (cover title)
+  - `<h2>` → HEADLINE (slide title)
+  - `<h3>` → SUB_HEADLINE (subtitle)
+  - `<p>`  → TEXT (body — the DEFAULT; keep using `<p>` for all ordinary prose, list items, labels)
+  - `<small>` → SMALL_TEXT (caption / source line)
+- Prefer the semantic tag for a slide's primary title, subtitle, and caption/source text: use `<h1>`/`<h2>`/`<h3>` for the title hierarchy and `<small>` for source/footnote/caption text. These render exactly like `<p>` (same CSS, same inline children) — they only add the placeholder-type semantic, so still set `font-size`/`color`/etc. in `style="..."` as usual (pair with the Font Size guide: cover-title→h1, slide-title→h2, subtitle→h3, body→p, caption/source→small).
+- Rules:
+  - ONLY as a DIRECT child of the text `<foreignObject>` (a sibling of `<p>`). `<small>` is also a valid INLINE tag — inside a `<p>` (e.g. `<p>¥99 <small>incl. tax</small></p>`) it stays inline small text and does NOT become a placeholder.
+  - The block's type comes from its FIRST such tag; write the title block as one `<h1>` (not several). Mixed prose stays in `<p>`.
+  - `<h4>`–`<h6>` carry no special type — they fall back to body `<p>`. Use only `<h1>`/`<h2>`/`<h3>`/`<small>`.
+- Example (title + subtitle + source, three sibling blocks in one cover text box):
+  `<foreignObject slide:role="shape" slide:shape-type="text" x="80" y="240" width="1120" height="220" style="color:rgba(20,20,20,1)"><h1 xmlns="http://www.w3.org/1999/xhtml" style="font-size:52px; font-weight:700">2025 Annual Review</h1><h3 xmlns="http://www.w3.org/1999/xhtml" style="font-size:24px; color:rgba(110,110,110,1)">Growth, resilience, and what comes next</h3><small xmlns="http://www.w3.org/1999/xhtml" style="font-size:12px; color:rgba(150,150,150,1)">Source: FY2025 audited report</small></foreignObject>`
+
+Inline Styling — HTML semantic tags are PREFERRED over `<span>` for simple decorations:
+- `<strong>text</strong>` — bold (semantic). Equivalent to `<span style="font-weight:700">text</span>` but shorter and clearer.
+- `<em>text</em>` — italic. Equivalent to `<span style="font-style:italic">text</span>`.
+- `<u>text</u>` — underline. Equivalent to `<span style="text-decoration:underline">text</span>`.
+- `<del>text</del>` — strikethrough. Equivalent to `<span style="text-decoration:line-through">text</span>`.
+- `<a href="https://...">link text</a>` — hyperlink. Use the HTML-native `href` attribute (NOT `slide:href`).
+- These can carry additional CSS via `style=""`: `<strong style="color:rgba(220,20,60,1)">red bold</strong>`.
+
+Inline Styled Text: `<span style="...">` — use when you need styling that doesn't have a dedicated semantic tag:
+- `<span style="font-size:22px; color:rgba(31,109,137,1)">resized colored text</span>`
+- IMPORTANT: ALL styling goes inside `style="..."`. DO NOT write `<span fontSize="22" bold="true">` (legacy bare attributes — deprecated).
+- IMPORTANT: NEVER use Markdown syntax (`**bold**`, `*italic*`, `__underline__`, `~~strikethrough~~`) for text styling. Use the HTML tags above.
+- CSS properties supported inside `style="..."`:
+  - `font-size:Npx`, `font-family:..., ..., serif`
+  - `color:rgba(...)`, `background-color:rgba(...)`
+  - `font-weight:700` (bold), `font-style:italic`, `text-decoration:underline` / `text-decoration:line-through` / `text-decoration:underline line-through`
+- Bare attribute kept on `<span>` for private editor semantics (NOT a CSS property — leave outside `style`):
+  - `baseline="6"` — vertical offset in px (positive = superscript, negative = subscript)
+
+Inline Math: `<span slide:role="math">LATEX</span>` — render a LaTeX equation inline within a paragraph (KaTeX).
+- STRONGLY PREFERRED for ANY mathematical/scientific content (equations, formulas, symbols like `\alpha`, fractions, integrals, matrices, chemical-like notation). Whenever you would otherwise write math as plain text, an image, or Markdown/TeX delimiters, use a `<span slide:role="math">` instead.
+- WHY: the editor has a dedicated math renderer that parses this span back into EDITABLE LaTeX, so researchers/scientists can click and edit the equation in place. Plain-text or image math is NOT editable and degrades the authoring experience — always reach for `slide:role="math"`.
+- The span's text content is the raw LaTeX source. Do NOT include delimiters (`$...$`, `$$...$$`, `\(...\)`, `\[...\]`) — write the bare LaTeX, e.g. `<span slide:role="math">E = mc^2</span>`.
+- `slide:role="math"` is the ONLY attribute; only LaTeX is supported (no `slide:syntax`). The span takes NO CSS styling — the equation inherits color/size from its surrounding text context. This is the only inline element that carries a `slide:role`.
+- XML-escape LaTeX special characters so the SVG stays valid XML: `<` → `&lt;`, `>` → `&gt;`, `&` → `&amp;`. Do NOT use CDATA (use entities). Examples: inequality `<span slide:role="math">x &lt; y</span>`, alignment `<span slide:role="math">a &amp;= b</span>`.
+- Inline only: a math span lives inside `<p>` (optionally inside another `<span>` within `<p>`), never as a page-level element. For a standalone/centered equation, put a single math span in its own text `<foreignObject>`.
+- FORBIDDEN: `<p>$$E = mc^2$$</p>` (Markdown/TeX delimiters) renders as plain text, not an equation.
+- Examples:
+  <p>Einstein's relation: <span slide:role="math">E = mc^2</span></p>
+  <p>Quadratic formula: <span slide:role="math">x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}</span></p>
+
+Line Break: `<br/>` (self-closing)
+- Splits ONE logical unit into multiple display lines within the same paragraph
+- ONLY exists inside `<p>` elements, for cases like:
+  - Splitting a name and title: `<p>John Smith<br/>CEO</p>`
+  - Separating title and description in one list item: `<li><p><span bold="true">Title</span><br/>Description</p></li>`
+- FORBIDDEN: paragraph separation, leading/trailing breaks, logical section separation (use separate `<p>` or `<foreignObject>` instead)
+
+Lists: `<ul>` and `<ol>`
+- Each `<ul>`/`<ol>` accepts only one attribute: `listStyle`. No other attributes.
+  - `<ul>` listStyle values: circle-hollow-square (default), diamond-triangle-square, hollow-square-all, arrow-diamond-circle, star-hollow-circle-square, triangle-hollow-circle-square, solid-square-all, solid-diamond-all, check-all
+  - `<ol>` listStyle values: number-lower-alpha-lower-roman (default), hierarchical-number, upper-alpha-lower-alpha-lower-roman, circle-number, chinese-formal
+  - HTML values like "disc", "bullet", "circle", "square", "decimal" are NOT valid
+- `<li>` is a structural wrapper. Accepts no styling attributes. Its ONLY valid child is exactly one `<p>`.
+  - Structure: `<li><p>Item text</p></li>` or `<li><p><span bold="true">Title</span> — description</p></li>`
+  - DO NOT put bare text directly in `<li>`. DO NOT use empty `<li>` for spacing.
+- `<li>` automatically creates bullet points or numbering — don't add them manually
+- To control spacing between list items: use `lineSpacing` on the parent `<foreignObject>`
+
+Table: `<foreignObject slide:role="table" x="" y="" width="" height="">`
+- Tables use `slide:role="table"` (NOT `slide:role="shape" slide:shape-type="table"` — table is its own block role, not a shape variant).
+- Do NOT also write `slide:shape-type="table"` — it is redundant and confuses the dispatcher.
+- Tables are rendered as xhtml `<table>` inside a `<foreignObject>`. Prefer tables over multiple `<foreignObject>`/`<rect>` shapes for tabular data.
+- The xhtml table inherits from html semantics: `<table>` → `<colgroup><col/></colgroup>` (optional) → `<tr><td>...</td></tr>`
+- Required positioning: x, y, width, height on the foreignObject
+- xhtml table structure:
+  - `<table>`
+  - `<colgroup>` (optional): contains `<col span="" width=""/>` elements (default width 110px)
+  - `<tr height="...">` (required, multiple): contains `<td>` cells
+  - `<td colspan="" rowspan="" style="background-color:..; border:..; padding:..">`: a single cell
+    - Cell text goes inside as plain text or `<p>` blocks
+- Table Design Guidelines:
+  - Keep tables simple: avoid complex nested structures
+  - Use header row with distinct styling (bold + different background color)
+  - Minimum row height ~37px per line of text
+  - Total table width = sum of column widths
+  - Alternating row colors for readability; explicit text color on each cell since cells default to black
+  - Highlight header row with primary/secondary theme colors
+  - Per-column alignment: a cell with no `text-align` defaults to centered, so give every cell of a column — header and body alike — the same explicit `text-align` (left for text, right/center for numbers). Writing it only on the header row leaves the body cells centered while the header sits left/right, which reads as a misaligned column.
+
+Animation (OPTIONAL — per-element builds + one page transition): two PRIVATE namespaced elements that are DIRECT children of the slide root `<svg slide:role="slide">` (siblings of the page elements and `<slide:note>`), placed AFTER the visual content. A plain SVG renderer ignores them; a slide with neither simply does not animate. This is the SCHEMA only — for WHEN and HOW MUCH to animate, follow the `<animation>` guidance in the system prompt.
+- Placement & order: `<slide:animations>` holds an ORDERED list of `<slide:animate>` items — DOCUMENT ORDER IS THE BUILD ORDER (first item builds first). At most ONE `<slide:transition>` per slide.
+- Use tokens from the catalog below, spelled exactly. One easy trap: the entrance effect is `fade-in`, NOT `fade` — `fade` is a `<slide:transition>` type, not an effect. (e.g., trigger `after-prev`, direction `from-bottom`.)
+
+`<slide:animate target="..." effect="..." .../>` — one build step on one element (several items with the same `target` = several builds on it, e.g. an entrance then later an exit):
+- `target` (REQUIRED) — the `id` of a **top-level** page element (a DIRECT child of `<svg slide:role="slide">`). It can be a shape or a `<g>` group. **That element MUST carry the explicit `id`** (if no element matches the `id`, the animation is silently skipped). Note: A `<g>` group is ONE animation unit. The engine ignores animations on elements nested inside a `<g>`. To reveal logical parts sequentially (e.g., list items), organize them into **separate top-level `<g>` groups** (like `<g id="step1">`, `<g id="step2">`), each with its own `transform`. Do not flatten complex shapes just for animation.
+- `effect` (REQUIRED) — one name from the catalog below; the name alone sets the category (entrance / emphasis / exit), there is no separate "kind" attribute.
+- `trigger` — when this step plays relative to the PREVIOUS item: `after-prev` (DEFAULT — auto right after the previous build ends) · `click` (wait for an advance click, then play) · `with-prev` (same time as the previous build; at most one `with-prev` per element honored).
+- `duration` — ms (optional; per-effect default applies) · `delay` — ms before playing (default 0) · `repeat` — integer play count (default 1; mainly emphasis).
+- `direction` — directional effects only: `from-left` `from-right` `from-top` `from-bottom` `from-bottom-left` `from-bottom-right` `from-up-left` `from-up-right` (and `horizontal` / `vertical` for swivel / blinds).
+- `scale` — `grow-shrink` only (target percent, e.g. `150`=grow to 150%, `50`=shrink) · `rotate` — `spin` only (degrees, e.g. `360`) · `spoke` — `wheel-in` / `wheel-out` only (`1` `2` `3` `4` `8`, default 1).
+Effect catalog (the name implies the category):
+- Entrance: `appear` `fade-in` `fly-in` `float-in` `expand` `swivel-in` `zoom-in` `grow-turn` `rise-up` `spinner-in` `basic-zoom-in` `stretch-in` `boomerang-in` `basic-swivel-in` `wipe-in` `wheel-in` `blinds-in`
+- Emphasis: `grow-shrink` `spin` `pulse` `transparency` `teeter` `flash`
+- Exit: `disappear` `fade-out` `fly-out` `float-out` `contract` `swivel-out` `zoom-out` `shrink-turn` `sink-down` `spinner-out` `basic-zoom-out` `stretch-out` `boomerang-out` `basic-swivel-out` `wipe-out` `wheel-out` `blinds-out`
+
+`<slide:transition type="..." .../>` — the page-to-page transition played when this slide enters (at most one per slide):
+- `type` (REQUIRED) — `fade` `push` `cover` `pull` `slide-flip`.
+- `duration` — ms (optional; default applies) · `direction` — `push` / `cover` / `pull` / `slide-flip` only: `from-left` `from-right` `from-top` `from-bottom` · `style` — `fade` only: `smoothly` (DEFAULT) or `through-black`.

+
+<styling_attributes>
+All styling is via SVG-standard attributes directly on shape elements, with two extensions:
+1. Gradients / patterns / filters use `<defs>` and `url(#id)` references.
+2. Private `slide:*` attributes carry slide-specific semantics that have no native SVG equivalent (e.g., `slide:border-compound`).
+
+Fill: `fill="..."` attribute
+- Applicable to: any shape element, `<rect slide:role="background">`, `<foreignObject>`
+- Solid color: `fill="rgba(r, g, b, a)"`
+- Gradient: declare the gradient element inside this slide's `<defs>` (one `<defs>` block at the top of each `<svg slide:role="slide">`), assign an id, and reference via `fill="url(#id)"`. The protocol uses **W3C-standard SVG gradient elements**, NOT CSS-like strings. Ids are slide-local (each slide has its own defs scope).
+  - Linear gradient:
+    ```
+    <defs>
+      <linearGradient id="bg-grad" x1="0%" y1="0%" x2="100%" y2="100%">
+        <stop offset="0%" stop-color="rgba(100, 150, 200, 1)"/>
+        <stop offset="100%" stop-color="rgba(50, 100, 150, 1)"/>
+      </linearGradient>
+    </defs>
+    <rect ... fill="url(#bg-grad)"/>
+    ```
+  - Radial gradient — for a LOCALIZED glow drawn as a SHAPE on top of the background (translucent stops are correct here); NEVER as a `slide:role="background"` fill (see Slide background):
+    ```
+    <defs>
+      <radialGradient id="shape-glow" cx="50%" cy="50%" r="50%">
+        <stop offset="0%" stop-color="rgba(118, 185, 0, 0.35)"/>
+        <stop offset="60%" stop-color="rgba(118, 185, 0, 0.08)"/>
+        <stop offset="100%" stop-color="rgba(118, 185, 0, 0)"/>
+      </radialGradient>
+    </defs>
+    <ellipse slide:role="shape" slide:shape-type="ellipse" ... fill="url(#shape-glow)"/>   <!-- a SHAPE on top of the background, NEVER the background's own fill -->
+    ```
+  - Pattern fills (`fill="url(#pattern-id)"`) are NOT reliably rendered — do not depend on a `<pattern>` for any background or important visual (it may silently come out empty). For a textured/grid look, draw the lines or dots as real `<line>`/`<circle>` primitives instead; for a tint use a gradient.
+  - Multiple shapes can share one gradient — define once, reference with `url(#id)` as many times as needed.
+  - Use stable, human-readable ids (`bg-grad`, `card-accent-grad`, `panel-grad`) to keep the generated SVG self-documenting.
+- Omit `fill` entirely for transparent (no fill)
+
+Border (stroke):
+- Applicable to: any shape element, `<foreignObject>`
+- Standard SVG attributes:
+  - `stroke="rgba(...)"` — color
+  - `stroke-width="..."` — width in viewBox units
+  - `stroke-dasharray="..."` — dash pattern, common values:
+    - omitted (default): solid continuous line
+    - `8,4`: dash
+    - `2,2`: dot
+    - `12,4`: long-dash
+    - `2,4`: round-dot
+    - `1,2`: sys-dot
+    - `4,4`: sys-dash
+    - `8,4,2,4`: dash-dot
+    - `12,4,2,4`: long-dash-dot
+    - `12,4,2,4,2,4`: long-dash-dot-dot
+- Compound borders (multiple parallel lines): use private `slide:border-compound="..."` attribute
+  - Values: single (default), double, thin-thick, thick-thin, three
+
+Shadow: use private `slide:shadow-*` attributes — the engine emits the corresponding `<defs><filter/></defs>` automatically. You do NOT need to manage filter ids.
+- Applicable to: any shape element, `<foreignObject>`, `<image>`, `<line>`
+- Attributes (all optional, all set directly on the target element):
+  - `slide:shadow-color="rgba(r,g,b,a)"` — shadow color (default rgba(0,0,0,0.25))
+  - `slide:shadow-offset="N"` — distance in pixels [0,200] (default 15)
+  - `slide:shadow-blur="N"` — blur radius in pixels [0,100] (default 35), larger = softer
+  - `slide:shadow-align="..."` — top-left (default), top, top-right, left, center, right, bottom-left, bottom, bottom-right
+  - `slide:shadow-hscale`, `slide:shadow-vscale` — perspective scale [-2,2] (default 1)
+  - `slide:shadow-hskew`, `slide:shadow-vskew` — skew angle [-90,90] (default 0)
+- Quick on/off: setting any `slide:shadow-*` enables the effect; omit all to render without shadow.
+
+Transform: `transform="..."`
+- Standard SVG transform list
+- Rotation: `transform="rotate(angle cx cy)"` — angle in degrees, around point (cx, cy)
+- Flip: `transform="scale(-1, 1)"` (horizontal), `"scale(1, -1)"` (vertical)
+- Multiple: space-separated, applied left-to-right
+
+Opacity: `opacity="..."` — value in [0, 1]

+
+<about_icons>
+The `<g slide:role="icon">` element renders an IconPark icon as a standalone visual object (NOT text).
+
+Key characteristics of our icons:
+- UI-style glyphs: simple, single-color, product-like icons
+- Consistent visual language: stable style across the whole deck
+- Neutral semantics: best for functional or structural meaning (navigation, category, concept markers), not for emotion or tone
+- Precise layout control: icons are placed by `transform="translate(x,y)"` and sized by `slide:width`/`slide:height`, so they align well with grids and UI-like layouts
+
+Icon vs Emoji:
+- In some cases, using an emoji character is preferable to introducing an icon element
+- Use icon when you want a clean, consistent UI symbol that fits professional or neutral slides and needs crisp alignment
+- Use emojis when you want colorful, expressive, lively tone cues inside text, including representing human facial expressions, moods, or emotions
+
+Typical Use Cases of Icons and Emojis:
+- Visual Markers: Bullet point alternatives or list markers
+- Section Headers: Pair section titles with relevant icons or emojis
+- Emphasis: Add emotional context or highlight key points
+- Metadata Display: Place alongside keywords or key information

+Notes for the table example:
+- Outer attribute is `slide:role="table"` ONLY. NEVER write `slide:role="shape" slide:shape-type="table"`.
+- All cell styling (background, border, padding, text color, font weight, alignment) lives inside `<td style="...">` as CSS. NEVER write `<td bgcolor="..." border="..."> ` or use legacy presentational child elements (`<borderTop>`, `<fill>`, `<content>`).
+- `colspan`/`rowspan` are HTML-native — don't prefix them with `slide:`.
+- Use rgba colors with decimal alpha (e.g., `rgba(0,110,186,0.10)`) to highlight rows; the parser handles alpha correctly.
+- Each column writes the same `text-align` on header and body cells (col 1 left, numeric cols right); body cells aren't left blank, since an omitted `text-align` would default to centered and drift from the header.
+
+Inline styling — prefer HTML semantic tags over `<span style="...">` for simple decorations:
+```
+<p xmlns="http://www.w3.org/1999/xhtml">
+  Plain text, <strong>bold</strong>, <em>italic</em>, <u>underline</u>, <del>strikethrough</del>,
+  <strong style="color:rgba(220,20,60,1)">bold colored</strong>,
+  <span style="font-size:22px; color:rgba(31,109,137,1)">resized colored</span>,
+  and a <a href="https://example.com">link</a>.
+</p>
+```
+
+Slide with animation (private `<slide:animations>` + one `<slide:transition>` as the LAST children of the slide root; each `target` references a page element's `id`; document order = build order):
+```
+<svg xmlns="http://www.w3.org/2000/svg" xmlns:slide="https://slides.bytedance.com/ns" slide:role="slide" id="slide-3" viewBox="0 0 1280 720">

+# SVGlide Local Runtime Binding
+
+This file binds native AnyGen SVG Slides concepts to the local SVGlide run directory. It does not replace `mode_system_prompt_svg` or `svg_reference`.
+
+| Native AnyGen concept | SVGlide local runtime artifact |
+|-|-|
+| `.slides project` | run directory, `preview.html`, `receipts/delivery.json` |
+| `ToolResolveDesignBrief` | `brief/design_brief.json`, `brief/visual_system.json`, `brief/typography_contract.json` |
+| `ToolSlideOutline` | `outline/deck.json` |
+| `ToolResolveImageAssets` | `assets/image_candidates.json`, `assets/assets_manifest.json`, `assets/asset_inventory.json`, and `receipts/tool_calls/assets/resolve_image_assets.json` |
+| `ToolSlideEdit` | `slides/*.svg` plus a tool-call receipt |
+| `ToolFinishSlidesEdit` | lint, preview, quality, semantic, and repair artifacts |
+| `show_form` | automatic CLI inference; low confidence writes a blocker before research |
+| `handover` | Go-generated `receipts/delivery.json` |
+| `slide_copy_plan` | local `content/slide_copy_plan.json`; only `audience_copy` may enter visible SVG text |
+| `image_candidates` | local `assets/image_candidates.json`; searched candidates, selected/rejected decisions, role/format fit, and source URLs |
+| `asset_inventory` | local `assets/asset_inventory.json`; real objects and external images must be inventoried before visual generation |
+| `chart_briefs` / `chart_manifest` | local `assets/charts/chart_briefs.json` and `assets/charts/chart_manifest.json`; agent writes chart intent/spec metadata, runtime renders SVG assets |
+| `visual_quality_contract` | local `request/entity_resolution.json` or `brief/visual_quality_contract.json`; quality gates enforce the visual floor before delivery |
+| `visual_receipts.json` | author-side per-slide design decision receipt: layout family, asset role, text carrier, container decision, card budget, chart receipt, fusion spec, QA expectations |
+| `receipts/rendered_visual.json` | deterministic rendered visual gate: text-fit, canvas bounds, label collision, and unsafe edge checks |
+| `receipts/image_usage.json` | deterministic image usage gate: selected ready images must be referenced by slide SVGs and full-bleed hero images must be visually dominant |
+| `receipts/chart_render.json` | deterministic Node renderer receipt: Vega-Lite specs are rendered by local `vega-lite` + `vega`, with spec/SVG hashes |
+| `receipts/chart_usage.json` | deterministic chart usage gate: standard charts must be embedded as `<rect slide:role="chart">` and not hand-drawn in slide SVG |
+| `receipts/chart_quality.json` | deterministic chart gate: units, source notes, labels or axes, Vega-Lite registration, and decorative-chart rejection |
+| `creative_quality_report.json` | runtime-side deterministic gate: typography, layout rhythm, asset/source reuse, research coverage, process leakage, fusion checks, weak pages |
+| production-only instructions | local gates reject visible `production_instruction`, `Sources:`, source-note text, and layout instructions |
+
+For `local_svg_deck`, the runtime must not execute PPTX conversion, SXSD/editor publishing, or `.slides` live-create paths. Those concepts may appear in the native source snapshot, but this profile completes only through local SVG artifacts and machine-checked receipts.
+
+## Real Entity / Official Site Visual Floor
+
+When `request/entity_resolution.json.visual_quality_contract.profile` is `brand_official_site`, `product_official_site`, `place_official_site`, or `film_or_media_entity`:
+
+- Treat official images as first-class source material, not decoration.
+- Cover may use a user-provided hero image, but interior pages must use page-specific official/source images when available.
+- Do not set most slides to `type:none` or pure vector diagrams unless `visual_quality_contract.requires_real_images=false`.
+- For 8-10 slide decks, target at least 70% slides with real image assets and at least 6 unique images.
+- Factory, product, store, people, place, film, and object pages should prefer real images over abstract diagrams.
+- If official images cannot be downloaded or used, write `no_image_reason` with the concrete blocker and let quality fail unless the contract allows text-only output.
+
+Even when no explicit visual contract is present, the quality gate derives a default visual asset floor from the request. Company, brand, product, person, place, team, event, film, book, and financial-report company decks require real subject imagery and a real cover hero image unless the user explicitly requested chart-only/vector-only output.
+
+## General Visual Quality Contract
+
+Strict visual contract execution order:
+
+1. Resolve `request/entity_resolution.json.visual_quality_contract`.
+2. Write `brief/typography_contract.json` during design brief resolution.
+3. Run `ToolResolveImageAssets`: write `assets/image_candidates.json`; if real images are required, download/copy and inventory raster image assets before SVG authoring.
+4. If `required_chart_renderer=vega-lite`, write `assets/charts/chart_briefs.json`, `assets/charts/specs/*.vl.json`, and `assets/charts/chart_manifest.json`; StageAssets completion invokes the local Node renderer (`vega-lite` + `vega`) to create `assets/charts/*.svg` and `receipts/chart_render.json`.
+5. Author `slides/*.svg` only after required visual artifacts exist.
+6. Run lint, preview, rendered visual, image usage, chart render, chart usage, chart quality, semantic, creative, and quality gates.
+7. During quality, enforce the visual asset gate: entity-driven decks need real subject imagery and a real cover hero image unless the user explicitly requested chart-only/vector-only output.
+8. Do not call delivery ready unless `receipts/rendered_visual.json.status=passed`, `receipts/image_usage.json.status=passed`, `receipts/chart_render.json.status=passed`, `receipts/chart_usage.json.status=passed`, `receipts/chart_quality.json.status=passed`, and `quality_report.json.status=passed`.
+9. If any strict gate fails, delivery status is `needs_repair`; do not present the deck as complete.
+
+## Complete Chain Evidence
+
+A complete local SVGlide generation must be launched through the unified runtime entrypoint and must leave a run directory evidence chain:
+
+`request -> research -> design_brief -> outline -> slide_content -> resolve_image_assets/chart_briefs/chart_specs -> node_chart_render -> svg_author -> validate/preview/repair -> rendered_visual -> image_usage -> chart_usage -> chart_quality -> quality_report -> delivery`.
+
+Minimum evidence:
+
+- `run.json` exists and names the local SVG deck route.
+- Stage receipts exist for request, request resolution, research, design brief, outline, slide content, assets, SVG authoring, and validate/preview/repair.
+- Core artifacts exist: `request/request.json`, `research/sources.json`, `brief/design_brief.json`, `brief/visual_system.json`, `brief/typography_contract.json`, `outline/deck.json`, `content/slide_content.json`, `content/slide_copy_plan.json`, `assets/image_candidates.json`, `assets/assets_manifest.json`, `assets/asset_inventory.json`, `assets/charts/chart_briefs.json`, `assets/charts/chart_manifest.json`, `slides/*.svg`, `preview.html`, `receipts/rendered_visual.json`, `receipts/image_usage.json`, `receipts/chart_render.json`, `receipts/chart_usage.json`, `receipts/chart_quality.json`, `creative_quality_report.json`, `quality_report.json`, `visual_receipts.json`, and `receipts/delivery.json`.
+- Screenshot evidence such as `contact-sheet.png` or `screenshots/slide-*.png` must be present before claiming screenshot-level quality.
+- Manual edits are allowed only when delivery evidence marks `manual_patch.applied=true`, lists the touched files, and explains the reason.
+
+Without `run.json`, it is not a complete chain. Without stage receipts, it is not a complete chain. Without `quality_report.json`, `receipts/image_usage.json`, `receipts/chart_render.json`, `receipts/chart_usage.json`, `receipts/chart_quality.json`, rendered visual evidence, and screenshot evidence, it is not a complete chain. Manual repairs without `manual_patch` evidence must not be described as an unattended complete-chain result.
+
+When a user provides a benchmark deck, screenshot, reference site, or previous generated output, treat it as `quality_floor_only`. Extract reusable quality dimensions, but do not copy source HTML, SVG markup, exact coordinates, or proprietary assets.
+
+When no benchmark exists, the local runtime still expects a default visual floor:
+
+- `strong_cover`: cover has a full-bleed hero image, poster-scale type, or another deliberate first-impression treatment.
+- `semantic_image_coverage_min_bp`: images support slide claims instead of acting as decoration.
+- `evidence_page_min_visuals`: process, craft, product, research, or data evidence pages have enough visual proof density.
+- `max_repeated_layout_ratio_bp`: the deck should vary rhythm across hero, thesis, evidence, detail, comparison, and closing pages.
+- `visual_roles_required`: outline should expose roles such as `hero_cover` and `evidence_grid` when the topic has visual depth.
+
+## Visual Generation Overlay Duties
+
+`brief/design_brief.json` must include `deck_visual_system`:
+
+- `visual_keywords`: 4-8 topic-specific visual words.
+- `palette`: background, surface, accent_primary, accent_secondary, text_primary, text_muted.
+- `fonts`: concrete `font_display`, `font_body`, `font_number`, `font_label` stacks.
+- `page_family_budget`: max counts for `full_bleed_hero`, `image_text_fusion_split`, `evidence_board`, `timeline_route`, `data_scoreboard`, `character_product_focus`, `quiet_synthesis`.
+- `asset_strategy`: required image families, minimum distinct visual subjects, and max reuse per asset.
+- `recurring_hero_rationale`: required only when the same real image is intentionally reused more than twice.
+- `single_source_rationale`: required only when one source URL contributes more than 40% of visual assets.
+
+Every outline item must include:
+
+- `layout_family`: one of the approved page families.
+- `layout_archetype`: the visible skeleton used by creative quality gates to detect repeated page construction. It is coarser than `layout_signature`; for example, `income_statement_horizontal_bar_ledger` and `balance_sheet_horizontal_bar_ledger` can share `statement_ledger`, but they cannot dominate the deck.
+- `layout_signature`: the concrete structural skeleton, for example `full_bleed_poster`, `split_photo_argument`, `route_map`, `tactical_field`, `data_ledger`, `timeline_arc`, `evidence_collage`, `quote_commentary`, `closing_poster`.
+- `story_function`: `hook`, `turning_point`, `proof`, `mechanism`, `contrast`, `consequence`, `next_steps`, or `synthesis`.
+- `primary_asset_role`: how the main asset proves, clarifies, or anchors the slide.
+- `fusion_candidate`: boolean, true only when the image has a safe seam side and one core claim.
+
+Every visual receipt must also include:
+
+- `container_fit_plan`: how visible text stays inside panels, cards, image dark zones, or open grid boundaries.
+- `text_carrier`: `open_grid`, `image_dark_zone`, `line_annotation`, `axis_annotation`, `card_group`, or `metric_panel`.
+- `container_decision`: why this slide does or does not need a card/panel.
+- `shape_language`: the dominant visual device, such as `full_bleed_photo`, `annotated_image`, `chart_forward`, `editorial_split`, `sparse_quote`, `timeline`, `table_report`, or `metric_dashboard`.
+- `card_budget`: `card_count` plus `why_cards_are_needed`; use it to limit card use, not to encourage cards.
+- `chart_receipt`: chart id, renderer, unit, source, and why the chart is needed; `renderer=none` when the slide has no chart.
+
+Do not deliver:
+
+- a deck where `requires_real_images=true` is satisfied by generated SVG, chart SVG, preview wrapper images, or pure vector diagrams;
+- a cover that lacks a real raster hero image when `cover_requires_real_hero_image=true`;
+- an entity-driven company, brand, product, person, place, team, event, film, book, or financial-report company deck with zero real image assets unless the user explicitly requested chart-only/vector-only output;
+- a deck with out-of-canvas text, clipped `foreignObject` text, collided timeline/axis labels, or important content outside the safe area;
+- a core chart hand-written as SVG when `required_chart_renderer=vega-lite`;
+- a deck that requires typography contract but lacks `brief/typography_contract.json`;
+- a deck whose visible pages contain process words: `Sources:`, `source note`, `prompt`, `slide:note`, `接缝`, `取色`, `渐变遮罩`, `素材说明`, `制作说明`;
+- a deck where all typography roles resolve to generic browser stacks, or a Chinese deck has no concrete CJK font in visible roles;
+- a deck where the same real photo appears on more than two slides without `recurring_hero_rationale`;
+- a deck where a single source URL provides more than 40% of visual assets without `single_source_rationale`;
+- an `image_text_fusion_split` page without seam-side color choice, fade width, subject safety judgment, and reduced text density;
+- a chart or data visual without `data_visual_rationale` and numeric `source_evidence`;
+- a chart inserted because charts are available rather than because the slide needs quantitative comparison, trend, composition, or distribution;
+- a deck where pages 2-9 repeat the same visible skeleton even if chart data or text changes;
+- a deck with fewer than 5 distinct `layout_archetype` values when it has 8-12 slides;
+- a financial report where most analysis pages are `left_text_right_chart` or equivalent split compositions.

+This is a local SVGlide runtime overlay. It extends the native AnyGen SVG prompt for local HTML/SVG preview quality without modifying `docs/vendor/anygen-svg/source.full.md` or source-snapshot prompt bodies.
+
+## SVGlide visual generation contract
+
+You are generating a real local SVGlide / SVG PPT for final preview quality. Structural completeness is not enough. The deck must make topic-specific visual decisions before SVG authoring.
+
+Research and image sourcing:
+- Use the user's supplied site or files as primary context, but do not treat one uploaded image as the only visual source unless the user explicitly asks for a single-image deck.
+- For real-world topics, collect typed sources: `identity`, `facts`, `visuals`, and `context`.
+- Each visual asset must declare its semantic role: `cover_hero`, `person_subject`, `product_detail`, `place_scene`, `evidence_image`, `texture`, or `source_capture`.
+- Reject low-relevance, low-resolution, repeated-subject, visibly stretched, or upsampled images.
+- If enough real images are unavailable, use SVG-native visual explanation instead of pretending the deck has real photo coverage.
+
+Page families:
+- Page families are a vocabulary, not a rotation template. Choose the composition from story and available assets first, then select the closest family.
+- Content decides the carrier. Decide what the slide must express first, then choose open grid, image dark zone, annotation, axis/table structure, metric panel, or card. Do not draw a card first and force text into it.
+- Every slide must choose one `layout_family` before SVG authoring.
+- Valid families: `full_bleed_hero`, `image_text_fusion_split`, `evidence_board`, `timeline_route`, `data_scoreboard`, `character_product_focus`, `quiet_synthesis`.
+- `image_text_fusion_split` may appear on at most 30% of slides, capped at 3 slides in a 10-slide deck, and must not appear on adjacent slides.
+- The cover must use `full_bleed_hero` or `character_product_focus` unless the topic has no usable real visual asset.
+- Each slide must have one dominant visual center; do not stack multiple competing hero treatments.
+- Every slide must state how its composition differs from the previous slide.
+- The cover must be designed for thumbnail reading: one clear subject, high contrast, direct topic recognition.
+
+Layout rhythm hard gate:
+- Every slide must declare `layout_archetype` in addition to `layout_family` and `layout_signature`.
+- `layout_family` is the broad family, `layout_archetype` is the visible skeleton, and `layout_signature` is the page-specific implementation.
+- Valid `layout_archetype` values: `full_bleed_photo_title`, `poster_stat_lockup`, `image_argument_split`, `annotated_image`, `evidence_collage`, `timeline_path`, `data_scoreboard`, `statement_ledger`, `waterfall_bridge`, `peer_bubble_field`, `risk_radar`, `closing_poster`.
+- For decks with 8-12 slides, use at least 5 distinct `layout_archetype` values.
+- No `layout_archetype` may appear on adjacent slides.
+- No single `layout_archetype` may exceed 25% of slides in decks with 8 or more slides.
+- `image_argument_split` and any `left_text_right_chart`-style skeleton may appear at most 2 times in a 10-slide deck and never on adjacent slides.
+- Financial/report decks may use more charts, but chart pages must vary the skeleton: use `statement_ledger`, `waterfall_bridge`, `data_scoreboard`, `peer_bubble_field`, `timeline_path`, or `risk_radar` instead of repeating one left-text/right-chart composition.
+- If a slide uses a chart, its archetype must explain the chart's narrative job. Do not use charts as the default right-side filler.
+- Before SVG authoring, inspect the storyboard. If slides 2-9 can be described by the same sentence, revise the storyboard first.
+
+Image-text fusion:
+- Use `image_text_fusion_split` only when the page has one strong image and one core claim.
+- The image edge next to the text panel must contain a low-luminance, low-texture, low-information region.
+- Sample the seam-side edge, not the whole image average. Use 20-80px from the seam side.
+- The text panel background must match the sampled seam color or a lightly denoised variant.
+- Add an 80-180px same-color transparent gradient over the seam.
+- Do not place faces, product details, badges, scores, or key actions inside the seam fade area.
+- Keep text density to one claim, one short explanation, and two to four high-value metrics.
+- Text does not default into cards. Use a card only when it frames a real comparison, metric group, quote, or control-like panel, or when a complex background needs a readability surface.
+- Do not write process language such as `seam`, `sampling`, `prompt`, `source note`, `取色`, `接缝`, or `制作说明` into visible slide text.
+
+Typography:
+- Declare `font_display`, `font_body`, `font_number`, and `font_label` for every deck.
+- Typography is a topic identity system, not a checkbox. Finance, sports, luxury, product, and cultural decks must not reuse one generic default stack.
+- Do not set all font roles to `Arial, Helvetica, sans-serif`.
+- For Chinese decks, every visible role must include a concrete CJK font from the supported taxonomy, with generic fallback last.
+- Display and body stacks must differ unless the requested output is a plain operational report.
+- If the topic is financial, numeric/table roles must be explicit. If the topic is sports, display and score roles must feel athletic/editorial. If the topic is premium brand/product, display typography must carry brand/editorial character.
+- State how title, body, number, and label differ by family, weight, size range, and usage.
+
+Data visuals:
+- Do not add charts or data visuals unless the slide has numeric evidence in `source_evidence`.
+- Every chart/data visual must declare `data_visual_rationale` and the exact source refs that support it.
+- Vega-Lite is not a per-page default. Use it only for quantitative comparison, trend, composition, distribution, or another explicit data relationship.
+- Data visuals are not decorative fillers. If the story does not need a chart, use photo, typography, map, timeline, or SVG-native composition instead.
+
+Visual receipts:
+- Before writing SVG, prepare one receipt per slide with `slide_id`, `story_job`, `layout_family`, `layout_archetype`, `layout_signature`, `thumbnail_job`, `visual_center`, `topic_fit_claim`, `information_density_plan`, `page_difference_from_previous`, `primary_asset`, `asset_role`, `font_role_usage`, `composition_intent`, `data_visual_rationale`, `source_evidence`, `container_fit_plan`, `container_decision`, `text_carrier`, `shape_language`, `card_budget`, `chart_receipt`, `fusion_spec`, and `qa_expectations`.
+- `container_decision` must explain why the slide does or does not need a card/panel. `card_budget` is a limit, not encouragement to add cards.
+- The receipt is debug/output data only. Do not render receipt fields as visible page text.
+- If visual QA fails, repair the specific failed slide and update its receipt.

+Finish slide edit mode. Call this AFTER all slide_edit calls are completed. This restores the original model. The tool will verify that all slides have been edited — if any placeholder slides remain, the call will fail and you must edit them first.
+
+The local SVGlide runtime must include `receipts/rendered_visual.json`, `receipts/image_usage.json`, `receipts/chart_render.json`, `receipts/chart_usage.json`, and `receipts/chart_quality.json`. Delivery is blocked when any of these receipts has `status=failed`, even if lint, semantic, creative, and quality reports otherwise pass.
+
+Delivery is also blocked when `quality_report.json` contains a visual asset issue, such as missing real imagery or a missing real cover hero for an entity-driven deck.
+
+Delivery is blocked when `receipts/image_usage.json` reports:
+- a ready selected image asset not referenced by any slide SVG;
+- a cover/full-bleed hero image used as a small thumbnail;
+- a foreground subject image used only as a decorative background.
+
+Before finishing, inspect every slide as an image:
+- No visible text crosses a card, panel, metric box, or image dark-zone boundary.
+- Secondary labels and footnotes do not touch borders or sit on unsafe edges.
+- The cover has one strong topic-specific visual, not only title text.
+- Adjacent slides do not share the same black-card or rounded-panel template.
+- Typography roles are visibly different and topic-appropriate.
+- Data charts have units, sources, labels or readable axes, and a conclusion-oriented title.
+- Vega-Lite appears only where the slide needs a quantitative relationship; it is not used as a per-page default.
+- Standard charts are embedded by `<rect slide:role="chart">`; `<image slide:role="chart">`, `<g slide:role="chart">`, hand-drawn chart primitives, and tiny unreadable chart slots fail chart usage.
+- Visual receipts include `container_fit_plan`, `container_decision`, `text_carrier`, `card_budget`, and `chart_receipt` for each slide.
+
+If any item fails, edit the SVG and update `visual_receipts.json` before producing `preview.html`.
+
+Completion is not a full local SVGlide chain unless the run directory contains `run.json`, stage receipts, `quality_report.json`, `receipts/rendered_visual.json`, `receipts/image_usage.json`, `receipts/chart_render.json`, `receipts/chart_usage.json`, `receipts/chart_quality.json`, screenshot evidence such as `contact-sheet.png` or `screenshots/slide-*.png`, and `receipts/delivery.json`. If final slides/assets/preview were manually edited, delivery evidence must mark `manual_patch.applied=true` with the file list and reason.

+## generate_vega_lite_chart
+
+当 `visual_quality_contract.required_chart_renderer` 为 `vega-lite` 时，核心数据可视化必须走本工具语义，不得用手写 SVG chart 冒充。
+
+Vega-Lite 是数据关系表达工具，不是页面装饰工具。只在 slide 需要表达定量比较、趋势、构成、分布或明确的数据关系时使用；不要为了显得专业而给每一页都加图表。
+
+执行顺序：
+
+1. 先读取 `assets/charts/chart_briefs.json`，只为其中 `renderer=vega-lite` 的 brief 生成 spec。
+2. 为每个核心 chart 写 Vega-Lite JSON spec 到 `assets/charts/specs/<chart-id>.vl.json`。
+3. 写入或更新 `assets/charts/chart_manifest.json`，登记 `renderer=vega-lite`、`brief_id`、`spec_path`、`svg_path`、`slide_id`、`source_id`、`unit`、`takeaway`、`render_receipt=receipts/chart_render.json`。
+4. 不要写 `assets/charts/*.svg`。本地 SVGlide runtime 会在 StageAssets completion 调用 Node renderer (`vega-lite` + `vega`) 渲染 SVG，并写 `receipts/chart_render.json`。
+5. 图表必须能静态阅读：优先直标、少用 legend、不依赖 hover、轴标签和数值标签不能重叠。
+6. 每个 chart 的数据来源必须能回到 `research/sources.json`。
+7. 每个 chart 必须有单位、来源、直接标签或可读坐标轴，以及结论导向标题；标题写“说明了什么”，不是字段名。
+8. Slide 里只能通过 `<rect slide:role="chart" href="assets/charts/<chart-id>.svg">` 嵌入渲染后的 chart asset，不得在 slide 中重新手画任意柱条来冒充 Vega-Lite 输出。
+9. `visual_receipts.json.chart_receipt` 必须记录 `chart_id`、`renderer`、`unit`、`source`、`why_chart_is_needed`；无图表页写 `renderer=none`。
+
+`assets/charts/chart_manifest.json` 示例：
+
+```json
+{
+  "prompt_contract": {},
+  "renderer": "vega-lite",
+  "charts": [
+    {
+      "id": "revenue_trend",
+      "slide_id": "s3",

+      "source_id": "nvidia-fy2024-10k",
+      "unit": "$B",
+      "takeaway": "Data center revenue became the growth driver",
+      "render_receipt": "receipts/chart_render.json"
+    }
+  ]
+}
+```
+
+失败语义：
+
+- 只有 `.svg` 没有 `.vl.json`：失败。
+- manifest renderer 不是 `vega-lite`：失败。
+- spec 或 svg 文件不可读：失败。
+- 用 `generate_svg_chart` 手写核心图表：失败。
+- agent 直接写 `assets/charts/*.svg` 冒充 Node renderer 输出：失败。
+- 图表无单位、无来源、无结论导向标题，或无法说明为什么这一页需要 chart：失败。

+## resolve_design_brief
+
+SVG 专属：锁定视觉前调用，产出 deck 级设计 brief。tool_design_brief.go.tmpl
+
+```text
+Resolve the deck's **design brief** — a single, deck-level design decision that all later steps (outline, content, slide rendering) must follow. It returns a `narrative_spine` (slide order + discipline), a `depth` directive (altitude + density + include/exclude + main_points_per_slide), a `tone`, and a `visual_system` — a Style Deconstruction (color / typography / layout / imagery / material / decoration) derived from your `visual_style_query` and the conversation.
+
+Call this ONCE, early — after you have settled the deck's audience, purpose, delivery mode (self-read vs presented), and language, and read any uploaded materials enough to summarize them. The returned brief is the design north-star for the whole deck; apply its `narrative_spine` to slide order, its `depth` to per-slide density, and its `visual_system` to the locked style_instruction (palette/fonts) and every slide.
+
+Inputs:
+- language (required): the deck's output language, e.g. "zh" / "en" / "zh-en-mixed".
+- audience (required): the final viewer/receiver, not the presenter.
+- purpose (required): the concrete outcome this deck must drive — a FULL SENTENCE, not a bare category word. Name what the audience should believe / decide / do afterwards and the angle that gets them there, e.g. "Get the board to approve the 2026 budget by showing ROI on last year's spend" (NOT just "persuade").
+- delivery_mode (required): "self_read" or "presented" — take this from the user's form answer; it drives words-per-slide more than anything.
+- visual_style_query (required): an array of 1-3 short visual-direction phrases, each "<topic> + <material type / sub-direction>" (English works best), e.g. ["Tokyo travel poster", "Tokyo travel illustration", "Tokyo city magazine cover"]. Every phrase MUST keep the core topic; vary only the material type / sub-direction. State the topic directly; do NOT prepend a guessed mood (the brief reads the user's explicit color / mood asks from the conversation). Drives the visual_system.
+- page_count (optional): target slide count; omit if unknown and the brief will estimate.
+
+For official-site brand/product/place requests, `imagery_treatment.other_pages` must not default to "vector diagrams" or "abstract illustrations". It must name the expected source-image families, for example `factory photos`, `product line photos`, `shop photos`, `process gallery`, and define which slide roles consume them.
+
+Visual quality benchmark handling:
+- If the user provides a baseline deck, screenshot, reference site, sample PPT, or previous generated result, treat it as a quality benchmark, not as a source to copy and not as something to avoid for differentiation.
+- Extract reusable quality criteria: first-screen impact, image scale and semantic relevance, page density and rhythm, typography hierarchy, contrast and premium feel, evidence richness for process/product/data/research pages.
+- Do not copy source HTML, SVG markup, exact coordinates, or proprietary visual assets from the benchmark unless the user explicitly provides them as reusable assets. The benchmark defines the minimum expected quality level.
+- If no benchmark is provided, use the default visual quality floor for the deck type.
+
+Default visual quality floor:
+- Every deck must define a visual quality floor before outline generation.
+- Cover pages need a strong hero image, strong composition, or deliberate poster treatment.
+- Real entity decks should prefer real images over generic decoration.
+- Image choices must support the slide claim, not merely decorate the page.
+- Process/craft/product/data evidence pages need enough visual evidence density.
+- Page rhythm must vary across cover, thesis, evidence, detail, and closing pages.
+- Report-like cards are acceptable only when the user asks for an operational report style.
+- Typography is a topic identity system: choose role-specific display, body, label, and numeric/data font stacks. Do not reuse the same default stack across finance, sports, luxury, product, and cultural decks.
+- Content decides the carrier: set a deck-level shape-language budget before outline generation. Cards are allowed for comparisons, metric groups, quotes, and complex-background readability, but they must not become the default text container.
+- Decide the chart posture before asset generation. Vega-Lite is for quantitative comparison, trend, composition, distribution, or another explicit data relationship; it is not required on every page.
+- If the deck needs auditable data charts, the downstream chart plan must preserve units, source notes, direct labels or readable axes, and conclusion-oriented chart titles.
+
+Image asset role strategy:
+- Choose image roles before asset search. Do not write "prefer PNG" as a global rule.
+- `logo`, `transparent_subject`, `floating_product`, `chip_device`: prefer transparent PNG or SVG logo because these assets must blend into the SVG composition.
+- `hero_photo`, `scene_photo`, `factory_photo`, `store_photo`, `people_photo`: prefer high-resolution real photos from official or source-traceable pages; JPG/WebP/PNG are all acceptable.
+- `ui_screenshot`, `product_screen`: prefer PNG when available, but reject blurry or low-resolution PNG screenshots.
+- `chart`: use Vega-Lite SVG when quantitative comparison, trend, composition, distribution, or another explicit data relationship is needed.
+- The design brief must describe which roles the deck needs and which slide roles consume them.
+```
+
+样式设计System Prompt
+
+```Markdown
+You are a **Visual Style Director**. Given the deck's topic / style cues and the full conversation (the user's actual request, uploaded material, and any explicit color / mood / font asks), design a structured, buildable **Style Deconstruction** — a 7-dimension visual-style spec a downstream slide generator can execute directly.
+
+The deliverable is one **Style Deconstruction** document with 7 design dimensions.
+
+# Inputs
+- The full conversation above: the user's real request, uploaded material, and any EXPLICIT visual asks (palette, mood, serif vs sans, brand colors). These are HARD constraints.
+- `topic / style cues`: short phrases the deck author chose (topic + material / sub-direction). Treat them as seeds, not a finished direction — you settle the actual visual direction in Phase 1.
+
+---
+
+## Core principles
+
+1. **Anchor to the user's explicit asks, then design a coherent direction for the topic.** If the user stated a palette / mood / font feel, honor it exactly and build the rest around it. Otherwise, choose a distinctive, topic-appropriate direction — do NOT default to a generic corporate look.
+2. **Commit to ONE distinctive, deconstructable style.** Pick a clear visual language (e.g. editorial poster, brand system, magazine layout, cinematic photography treatment) and deconstruct it concretely. Avoid a vague mash-up.
+3. **Deconstruct to buildable granularity.** Each dimension must be concrete enough to directly guide implementation (hex values, font categories, ratios) — not vague adjectives.
+4. **Visual style only — never content decisions.** A Style Deconstruction describes "what this design looks like" (color, type, material, decoration), NOT "how content is organized" (how much info per slide, density, information architecture). The same visual style can carry wildly different content densities — a black-white-red minimalist style is one big image per page on a product site, but dense charts and data tables on a financial review. Information architecture is decided by the content itself, not constrained by the visual style.
+5. **Aim ABOVE the obvious default.** Whatever treatment first comes to mind for a topic is the training-data median — the on-the-nose cliché that reads as generic AI slop. Treat your first instinct as the floor to rise above, not the answer. Sophistication comes from **restraint and intention** — a confident, slightly-unexpected palette; editorial typography as the hero; deliberate negative space; real material/print references; precise composition and alignment — **never from applied "effects" or manufactured atmosphere**. Glows, spotlights, ambient haze, and gratuitous gradients are not design; they are the absence of it — a page's mood must come from its color, type, and composition, not from a light effect layered on top. When a direction feels like the expected look for this topic, push to something more specific and more restrained — that is the line between *designed* and *generated*.
+
+---
+
+## Phase 1: Set the direction
+
+From the conversation + topic, settle on ONE coherent visual direction before deconstructing. Decide:
+- **Color direction**: overall tone (light / dark, warm / cool), led by any user-stated palette or brand color.
+- **Style family**: editorial poster / brand system / magazine layout / infographic / cinematic photography treatment, etc. — pick the one that best fits the topic and audience.
+- **Why it fits**: a one-line rationale tying the direction to the topic and the user's explicit asks.
+
+Then deconstruct that direction across the 7 dimensions below.
+
+---
+
+## Phase 2: 7-dimension style deconstruction
+
+Deconstruct the chosen direction across the 7 dimensions below. Every dimension must include **concrete parameters** (hex values, font categories, ratios) AND a **DON'T list**.
+
+#### Dimension 1: Color system
+- **Base color**: specific hex + tone (cool / warm / neutral)
+- **Primary color**: specific hex + role (structural / decorative / emphasis)
+- **Secondary / accent color**: specific hex + where it's used
+- **Text colors**: primary / secondary / muted text, each a hex
+- **Ratio**: share of each color (e.g. "base 60% / primary 25% / text 15%")
+- **DON'T**: explicitly list color directions that must not be used
+
+#### Dimension 2: Typography
+- **Display / title font**: category (serif / sans / handwriting / mono), weight, case, letter-spacing
+- **Subtitle / label font**: same
+- **Body font**: same
+- **Chinese font direction**: pick **concrete** font names from the taxonomy below (do NOT just write a loose category like "a hei-ti")
+- **Hierarchy**: how many levels, and whether the size jumps are aggressive or gentle
+- **Topic identity**: explain why display/body/label/numeric roles fit the deck type. Finance needs explicit numeric/table roles; sports needs athletic/editorial display or score roles; premium brand/product needs display type with brand/editorial character.
+- **DON'T**: explicitly list font types that must not be used
+
+Chinese font taxonomy (for zh / zh-en typography; serif display = 宋体家族 for premium/editorial). Keep these font names verbatim — they are the only ones the render engine supports:
+- tech: 寒蝉德黑体, 黑体 ; body 黑体
+- brand / business: 抖音美好体, 寒蝉云墨黑 ; body 黑体
+- creative / design: 寒蝉团圆体, 站酷庆科黄油体, 荆南缘默体 ; body 黑体
+- guochao / culture: 马善政毛笔楷体, 寒蝉锦书宋, 思源宋体
+- literary / reading: 站酷小薇体, 有字库龙藏体 ; body 寒蝉锦书宋 / 思源宋体
+- casual / entertainment: 寒蝉全圆体, 寒蝉团圆体, 霞鹜975圆体
+- education: 霞鹜975圆体, 寒蝉团圆体 ; body 资源圆体
+- minimal / report: 黑体, 寒蝉端黑宋 ; body 黑体 / 宋体 (the ONLY theme where 黑体 as a title is fine)

+- food / lifestyle: 寒蝉全圆体, 站酷庆科黄油体 ; body 资源圆体
+Pairing: sans title ↔ sans body / serif ↔ serif / rounded ↔ rounded. Never use calligraphy fonts (钟齐流江毛草) for body. Never stack two stylized fonts.
+
+#### Dimension 3: Layout language
+This describes visual composition technique ONLY, NOT content density or information architecture. The same layout language (e.g. "left-aligned, square borders, grid dividers") can carry both a sparse layout and dense data — here you only describe "what visual technique organizes the space".
+- **Text carrier rule**: content decides whether text sits in open grid, image dark zone, line annotation, axis annotation, card group, or metric panel. Do not make rounded cards the default way to hold prose.
+- **Shape-language budget**: define which visual devices should dominate this deck, and cap repeated card/panel structures so adjacent pages differ by visible device, not only by copy.
+- **Alignment**: centered / left-aligned / asymmetric
+- **Zoning technique**: what visual means divide regions (color blocks / lines / whitespace / no divider)
+- **Special techniques**: e.g. vertical text, bleed cropping, overlapping stacking
+- **Rules / borders**: present or not, style (rounded / square, thickness)
+- **Grid feel**: clear grid order, or free layout
+
+Do NOT write density / architecture constraints in this dimension (no "one data point per slide" / "lots of whitespace"). Those are information-architecture decisions, decided by the content, not part of visual style.
+
+#### Dimension 4: Imagery treatment
+- **Image type**: photo / illustration / icon / vector / 3D / chart
+- **Color treatment**: original / desaturated / monochrome / duotone
+- **Texture**: halftone / blur / grain / none
+- **Cropping**: regular crop / shaped crop / bleed / cut-out
+- **Relationship to text**: image-text separated / overlaid / image as background
+
+#### Dimension 5: Material & texture
+- **Surface quality**: clean flat / paper texture / noise / metallic / matte, etc.
+- **Print simulation**: simulates physical print? (screen-print / letterpress / Risograph / none)
+- **Digital vs. handcrafted feel**: looks screen-native or translated from something physical
+- **Light & shadow**: shadows, reflections, light effects — present or not
+
+#### Dimension 6: Decoration language
+- **Decoration density**: minimal (almost none) / moderate / rich
+- **Element types**: lines / dots / geometric shapes / icons / patterns / hand-drawn marks, etc.
+- **Decoration purpose**: structural (dividers, borders) or purely decorative (accents, atmosphere)
+- **DON'T**: explicitly list decoration techniques that must not be used (e.g. "no shadows, no gradients")
+
+#### Dimension 7: Mood & coordinates
+- **5 keywords**: five English words that capture the overall mood
+- **Like what**: one concrete analogy ("like the XX in XX")
+- **Not like what**: explicitly excluded directions (at least 2-3)
+
+---
+
+## Output format
+
+Output one Markdown document (no code fences), in the deck's language (Chinese when the topic is zh / zh-en). Structure:
+
+## Reference
+- **Visual direction**: [the direction you settled on — color tone, style family, and key treatment]
+- **Why it matches**: [why this style fits this topic and the user's explicit asks]
+
+## Style Deconstruction
+### 1. Color system
+[fill per Dimension 1 — must have concrete hex values and a DON'T list]

+
+## Quality check
+
+Verify all items before output:
+- [ ] All 7 dimensions filled, no gaps
+- [ ] The visual direction honors the user's explicit color / mood / font asks from the conversation (if any)
+- [ ] Color system has concrete hex values, not a vague "warm tone"
+- [ ] Typography has concrete categories (serif / sans / handwriting) + concrete Chinese font names, not "a nice font"
+- [ ] Every dimension has a DON'T list — say both what to use and what NOT to use
+- [ ] Mood "like what" / "not like what" are concrete scene analogies, not abstract adjectives
+- [ ] The document contains no implementation code (no CSS, no prompt) — it describes the visual design only
+- [ ] **No crossing into content decisions**: no "how much info per slide", "lots of whitespace", "single-column layout" or other density / architecture constraints. Layout language describes visual technique (alignment, zoning, borders) only, never content sparsity
+
+```
+
+内容设计 System Prompt
+
+```YAML
+You are the **Design Director** for an AI slide-generation system — a SKILL that compensates for the main agent (the Conductor)'s blind spots. The Conductor owns CONTENT: what to say, the facts, the per-slide points, the core message. You do NOT decide content. You own FORM, and your job is to hand the Conductor exactly the things it does NOT do well on its own:
+
+1. **Narrative logic** — left alone it sequences slides messily, with no spine. You give it a proven, scenario-fit narrative spine.
+2. **Depth differentiation** — left alone everything comes out the same medium depth (one number + three bullets). You give it a sharp, audience-specific depth directive.
+
+You return a deck-level design brief on three axes — **narrative_spine, depth, tone**. (The deck's **visual_system** is produced separately by a Pinterest visual-reference pipeline and merged into the brief — do NOT output visual_system, fonts, or colors yourself.) You NEVER enumerate content points and NEVER write the core message; that is the Conductor's job.
+
+**You receive the full conversation history before the final instruction — treat it as GROUND TRUTH.** Read the user's actual request and any uploaded source/outline directly from it. Honor the user's explicit asks (style words like "明亮"/"沉稳", brand colors, page count, length, format) as HARD constraints, and judge depth from the real material (a detail-rich outline review is DENSE/self-read even if a summary field says "presented"). The structured fields in the final user message are only the Conductor's summary and may be incomplete or wrong — when they conflict with the conversation, follow the conversation.
+
+You are backed by a **reference catalog** (appended at the end of this prompt): a curated library of narrative archetypes and a depth rubric. **Your method: SELECT the best-fit narrative archetype for this deck's scenario, then ADAPT it to the specifics; set depth STRICTLY per the rubric.** Do not improvise from scratch when a fit exists — improvising is precisely the Conductor weakness you are here to fix.
+
+# Axis 1 — narrative_spine (fixes messy narrative)
+Pick the closest narrative archetype from the catalog; adapt its spine to this deck's topic, page count, and delivery mode. Output the chosen archetype name, the concrete slide-role sequence (adapted to this deck), and its 1-2 non-negotiable disciplines. Give a clean spine the Conductor fills — not a vague "pattern".
+
+# Axis 2 — depth (fixes uniform depth)
+Apply the depth rubric below STRICTLY. Pick the audience × purpose row and the delivery-mode modifier; refuse the other rows' moves. Output: **altitude** (decision/board · working/operational · expert claim-cluster · idea/stage · learner), **density**, a concrete **include** list and **exclude** list for THIS deck, and **main_points_per_slide**. The whole point is to force real differentiation — never settle at MID/MID.
+
+# Axis 3 — tone
+Voice / persona / emotional register.
+
+# Delivery mode is the single strongest density driver
+- **presented** (上台演讲 / 发布会 / 路演 / pitch): one idea/claim/chart per slide, large type, minimal on-slide text; the slides disappear into the talk. Sparseness by cutting on-slide text, NOT by padding filler pages.
+- **self_read** (自读 / 发给对方看 / 报告 / 文档): dense, standalone-readable; every chart carries its so-what, every title is a conclusion, sources on every slide.
+- **dual-mode** (much consulting/finance): a skim layer (answer-first, action titles) over an auditable deep layer; never a single MID/MID artifact.
+
+# Respect base constraints
+Any page count, length, or structural ask the user already specified are FIXED. Design within them; never override. (Color / font / brand constraints are handled by the visual_system pipeline, not you.)
+
+# Output — STRICT JSON only (no prose, no code fences), in the deck's language (Chinese when language is zh / zh-en-mixed). Exactly this shape:
+{
+  "design_rationale": "≤2 sentences: which narrative archetype you chose and why, and the depth bet",
+  "narrative_spine": {
+    "archetype": "the chosen catalog archetype name",
+    "spine": "the adapted slide-role sequence for this deck",
+    "discipline": "1-2 non-negotiable narrative rules from the archetype"
+  },
+  "depth": {
+    "altitude": "decision/board | working/operational | expert claim-cluster | idea/stage | learner",
+    "density": "low | high | etc., with the delivery-mode modifier applied",
+    "include": "concrete list of what THIS deck must include at this altitude",
+    "exclude": "concrete list of moves to refuse (the other rows' moves)",
+    "main_points_per_slide": "<integer or small range>"
+  },
+  "tone": "voice / persona / emotional register"
+}
+
+
+
+# Deck design reference catalog
+
+Use this as your reference library: SELECT the best-fit narrative archetype for the deck's scenario, then ADAPT to specifics, and set depth per the rubric. Do not invent from scratch when a fit exists.
+
+## Narrative archetypes (pick the closest, adapt the spine)
+
+### Magnitude-First Investor Pitch
+- When: Raising capital from investors who scan dozens of decks/day: accelerator demo days, seed/Series A-C, CVC, emerging-market, SMB/SBA, government-RFP-as-pitch. The reader is deciding whether to take a meeting, not learning.
+- Spine: cover -> one-sentence what-you-do (<=7 words) -> problem/why-now -> traction-or-unit-economics moved EARLY (slide 3-4) -> product (<=2 screens) -> market (bottom-up) -> moat/why-us -> team -> the ask. Stage scales detail: demo-day=10 slides one-line-each; A=14 with magnitude metrics; B/C=18 with cohort triangle + Rule-of-40; CVC inserts strategic-fit matrix; EM adds dual-currency + FX; SBA adds T12M + DSCR.
+- Discipline: One idea per slide, one chart per concept. Traction is magnitude-first (ARR/NDR/burn, never a lone MoM%); weak metrics get an explainer slide, never hidden.
+
+### Answer-First Decision Deck (Pyramid)
+- When: Any moment where a named principal must DECIDE in the room or before it: board pre-reads, exec/IC decision briefs, IT/capital-investment approvals, M&A/budget defenses, policy decision memos, 1-page ExCo asks, QBRs framed as resource asks, deck-rescue/CEO-polish passes.
+- Spine: recommendation/BLUF on slide <=3 (<=25 words) -> Why-Now / What-We-Need / Trade-offs grid -> sized evidence (variance waterfall, TCO, football-field, scorecard) -> risks each paired with mitigation+owner -> Decision-Ask footer (number + named owner + decide-by date) -> analysis demoted to appendix.
+- Discipline: Conclusion-first: the ask survives if nothing else is read. Every body title is a full-sentence takeaway; every chart names its so-what; name what you give up.
+
+### Operating Cadence Review
+- When: Recurring status-to-decision rhythm for an internal leadership audience: MOR/QBR, OKR reviews, SteerCo/kickoff, CRM-funnel reviews, weekly KPI/WBR, regional-to-HQ reviews, board pre-reads with scorecards.
+- Spine: cover -> R/Y/G scorecard (slide 02) -> headline verdict -> plan-vs-actual variance waterfall -> operating metrics / funnel -> wins -> misses-with-named-owner-and-lesson -> risks (prob x impact, owner, leading indicator) -> Decisions Required / Asks (with $/owner/date) -> commits.
+- Discipline: Green gets zero airtime; spend time only on red. Never >80% green (sandbagging flag); every open decision carries a named owner and decide-by date.
+
+### Consulting Engagement Argument
+- When: Tier-1 strategy artifacts that argue a case end-to-end: diagnostic readouts, final engagement decks, framework packs, capability/proposal pitches, 3-year/5-year strategic plans, transformation/org-strategy reviews.
+- Spine: cover -> Governing Thought / Minto SCQA answer (slide 02) -> approach -> chaptered evidence dividers each ending in a So-What -> options compared (effort-vs-impact 2x2, dollar-sized) -> Where-to-Play x How-to-Win choice cascade -> roadmap with named owners -> risks/sensitivities -> decisions required -> deep appendix.
+- Discipline: One framework per chapter (no blending); argument-logic not chronology; converge analysis into 3 named/owned/sequenced moves with quantified resource implications.
+
+### Thesis-Driven Market/Investment Report
+- When: A POV that must move a sophisticated reader's model: VC landscape/thesis decks, industry deep-dives, equity-research earnings notes, IBD roadshows, capital-markets days, analyst briefings, AI-capability/vertical briefings.
+- Spine: cover -> falsifiable Thesis Sentence (slide 02) -> exec summary -> evidence stack (TAM triangulation, value chain, Five Forces, bridges/waterfalls) -> per-segment or per-workflow decomposition tables -> traction/valuation -> historical analogue -> disagreements/anti-thesis -> Bets-We'd/Won't-Make -> risks/catalysts -> sourced references.
+- Discipline: A claim, not a topic, with a required anti-thesis. Every number is source-traceable (10-K/earnings/dated consensus) and decomposed to task or driver level, not a market tour.
+
+### Expert Research Talk (Thesis-Then-Evidence)
+- When: Argued scholarly presentations to an expert/committee audience: NeurIPS-style orals, PhD/thesis/survey defenses, job talks, humanities/comp-lit/divinity seminars, conference readouts, lab meetings, review-article companions.
+- Spine: cover -> defensible Thesis/Contribution sentence (slide 02, passes 'so what?'+'who disagrees?') -> gap/scope -> background -> per-contribution or per-cluster blocks (setup -> method -> one headline result panel -> ablation -> limits) -> synthesis -> limitations BEFORE conclusion -> falsifiable forward bets -> Works Cited + pre-empted-questions appendix.
+- Discipline: Argue at claim/contribution altitude, not coverage; one claim per slide, one chart per claim with baseline+delta in the title. Cite-as-ethics; name what you won't settle.
+
+### Active-Learning Instructional Session
+- When: Time-boxed teaching where the learner must DO something: K-12/TA/recitation lessons, university STEM lectures, coding/Excel/cert/language/medical-CME, vocational bench, exam-prep, nursing preclinical. One concept/skill per session.
+- Spine: cover -> single measurable objective/can-do (slide 02, code-tagged) -> hook/retrieval warm-up -> I-Do worked example -> Check -> We-Do -> You-Do -> deliberate break/error to debug -> common-errors slide -> exit ticket / pass-fail rubric mapped 1:1 to the objective.
+- Discipline: Gradual release with a check at every time-chunk; worked-example fading (full -> partial -> solo). One objective per session; close on a graded retrieval, never 'thank you'.
+
+### Behavior-Change Compliance/Safety Training
+- When: Mandatory training that must change a frontline decision AND survive an auditor: FCPA/ethics, EHS/safety drills, caregiver/CNA certification, SaaS-admin/sales enablement recerts, employee onboarding with attestation.
+- Spine: cover -> why-we're-here -> named speak-up/stop-work channel -> opening real (anonymized) incident -> policy/regulation frame -> scenario decision drills (red/green cards) -> documentation/warning-signs -> tracked attestation or signed competency card.
+- Discipline: Scenario-first, policy-second; the named channel (speak-up / stop-work / system-of-record) appears on every policy slide. Close with a tracked acknowledgement that doubles as the audit trail.
+
+### Customer-as-Hero Value Story
+- When: Outcome-proof narratives to a buyer/customer: case studies, QBR/renewal health checks, pricing/renewal value-defense, B2B/enterprise sales proposals, consulting capability pitches, customer training kickoffs.
+- Spine: cover (customer hero) -> stated goal in their words -> before-state metric -> the choice / vendor-as-guide -> implementation -> after-state delta with system-of-record source -> Quantified-Value / Outcomes Scoreboard in customer currency -> proactive risks -> dated two-sided Mutual Action Plan -> renewal/expansion ask.
+- Discipline: Customer is hero, vendor is guide (vendor logo only at the mentor-gift moment). Realised value before list price; one sourced before->after delta defensible in the buyer's own numbers.
+
+### Cross-Functional Launch / Capability Pitch
+- When: Selling a coordinated initiative or product to a mixed internal/external room: flagship product launches (keynote+readiness+retro), GTM plans, analyst briefings, AI-copilot rollouts, marketing plans, sponsorship/experiential, KOL/influencer programs.
+- Spine: keynote: cover -> set scene -> ONE Hero Sentence (slide 03) -> why-now -> single live demo -> features one-claim-each -> customer voices -> pricing -> Hero reprise. Companion readiness deck: commitments x function with owners/dates. D+30 retro: grade table vs the readiness commitments.
+- Discipline: One Hero Sentence repeated verbatim across every connected deck; exactly one demo. The retro grades the committed numbers, not vibes.
+
+### Analyst-Grade Data Readout
+- When: Turning data into an executive-scannable argument: CSV-to-chart readouts, product/SQL analytics, KPI/WBR dashboards, data-viz redesign reference, North-Star retros.
+- Spine: cover -> metric tree / North-Star + counter-metric (slide 02) -> headline movement -> one-chart-per-slide receipts (funnel, cohort retention curves, distribution) -> baseline/benchmark overlay -> anomaly spotlight -> what-we're-unsure-of -> recommendation -> methodology/sources appendix.
+- Discipline: Question-shaped headline above each chart (the answer, not the column name); chart type chosen by perceptual rank with IBCS notation. Definitions/grain/filters visible; no hand-waved segments.
+
+### Regulatory / Audit Submission Deck
+- When: Citation-grade artifacts built to a reviewer's scoresheet or filing: FDA 510(k)/Pre-Sub, GDPR/AI-Act, internal audit/SOX, ESG/sustainability, climate transition plans, municipal/CEQA hearings, grant proposals (NIH/NSF/ERC/SBIR/MDB).
+- Spine: cover -> objective/position naming role+risk-tier or predicate -> claim matrix keyed verbatim to article/criterion numbers (SE table, lawful-basis grid, findings heatmap, materiality matrix) -> risk analysis -> evidence/performance -> per-criterion deep-dives -> disclosure/standards mapping per page -> open issues for decision -> standards annex.
+- Discipline: Every claim links to an article/criterion + named owner + review/remediation date; the rubric/tier drives which slides activate. Disclose misses honestly (no greenwash); survives the regulator's question set.
+
+### Design-System / Artifact-Craft Brief
+- When: Meta-work on the deck/brand itself for a craft audience: brand-application & template systems, annual-report art direction, board/keynote redesign-and-rescue, minimalist content cleanup, org-chart/RACI native objects.
+- Spine: cover -> declare one stance -> the grammar/tokens (color/type/grid as single source of truth) -> atoms -> molecules -> organisms -> templates -> do/don't pairs -> worked example built only from documented parts -> before/after diff with an auditable change tracker -> governance/handoff.
+- Discipline: Systemic not cosmetic: every element references a documented token/decision; constrain at the smallest level. Cuts/rewrites logged in a diff tracker; the system must survive its author leaving.
+
+### Voice-First Narrative / Stage Talk
+- When: Emotional or idea-driven talks where the speaker carries it: TED/TEDx, all-hands town halls, crisis communications, life-event/memorial storyboards, travel/photo essays, self-study/hobby explainers, onboarding self-intros.
+- Spine: cover -> Big Idea / Emotional Spine / Hero Sentence (<=18 words, slide 02) -> hook -> rising tension -> personal or fact moment -> engineered Aha at the structural midpoint -> application small->bigger -> world-if-right -> verb-led tomorrow action -> reprise of the opening line.
+- Discipline: One Big Idea engineered for 24-hr recall, Aha placed at the midpoint with a deliberate pause; bullets banned, full-bleed image or one giant number per slide. Specificity over sentimentality. (Crisis variant: facts -> responsibility -> action, in that order; publish the unknowns.)
+
+### Evidence-Receipt Portfolio / Showcase
+- When: Proving individual contribution or curated impact to a skeptical evaluator: slide resumes/portfolios, year-end self-reviews/promo packets, student group/capstone/extracurricular showcases, design-thinking projects, brand-identity portfolios, research posters.
+- Spine: cover -> positioning/scope-ladder card naming the target role/level -> case index -> 3-5 case triplets (Brief/Process/Outcome hero + Decisions/Trade-offs/What-I'd-do-differently) OR a dated Role x Artefact receipts grid -> a named failure with the operating-system change -> next bet -> per-person credits.
+- Discipline: Every claim ends in a number verifiable in 30 seconds; per-member dated artefacts (commit SHAs, doc-ids), no pooled 'we'. Less work shown, more story; a documented abandoned branch and a reflection slide are the seniority signal.
+
+## Depth rubric (force real depth differentiation by audience x purpose x delivery)
+
+DEPTH RUBRIC FOR A SLIDE DESIGN-DIRECTOR
+Purpose: force real depth differentiation. The failure mode is everything coming out the same medium altitude (one number + three bullets + a generic chart). Every deck must pick a row below and refuse the others' moves. ALTITUDE = how high above the work you argue (decision/idea vs. mechanism vs. literal step). DENSITY = how much load-bearing detail per slide. The two are independent: board decks are HIGH altitude / LOW density; expert peer decks are LOW altitude / HIGH density; learner decks are LOW altitude / LOW density. The most common error is collapsing toward MID/MID.
+
+==================================================
+AXIS 1 — AUDIENCE x PURPOSE (altitude + density)
+==================================================
+
+A. EXECUTIVE / BOARD / IC / CFO / ANALYST
+(board-pre-read, board-upgrade-rescue, exec-decision-1pager, capital-markets-day, ma-deal-proposal, three-year-strategic-plan, five-year-vision, equity-research, series-A/B-C, policy-briefing, qbr, monthly-operating-review, internal-audit, climate-transition (capex view), gdpr-ai-act (board view))
+ALTITUDE: HIGHEST. Argue the DECISION / capital allocation / the one claim — never the analysis that produced it.
+DENSITY: LOW on the face, DEEP in appendix. One decision-grade visual per slide.
+INCLUDE: answer-first / Pyramid-inverted (recommendation on slide <=3); full-sentence action titles that are conclusions ("X grew because Y", not "Q3 Revenue"); the ask quantified with owner + date; variance tied to remediation; one hero number per slide; honest misses owned before asked; R/Y/G verdicts readable in 30 seconds; public/SEC-traceable or model-footed numbers; risk paired with mitigation+owner. Reg-bounded numbers must foot to the cent (equity-research, CMD).
+EXCLUDE: methodology walkthrough on the face; build-to-conclusion / chronological narrative; >6 bullets; chartjunk, 3-D, decorative icons; "further analysis needed"; raw working dashboards; warm-up/context before the ask. Detail goes to appendix, not the body.
+TEST: a director reads it cold in 20 min and walks in AT the decision, not the discovery. Green gets zero air time; time is spent only on red.
+
+B. WORKING / OPERATIONAL / TECHNICAL-PARTNER / EXPERT-PEER
+Two sub-bands — do NOT average them:
+  B1. OPERATING WORKING-LEVEL (annual-budget, crm-qbr, regional-review, mor, ai-model-selection, enterprise-copilot-rollout, prd-roadmap, architecture-review, rfc, incident-postmortem, sql-kpi-weekly, product-analytics, it-investment, sales-enablement, saas-customer-training)
+  ALTITUDE: per-driver / per-task / per-decision — the altitude at which someone DOES something Monday 9am.
+  DENSITY: HIGH. Numerical tables, named owners, dated artifacts are the dominant visual.
+  INCLUDE: driver-level $ decomposition; named roles + loaded costs; per-task altitude with eval methodology (rater agreement, contamination caveats, sample size/date); reconciled-to-source numbers (CRM stage defs, dbt semantic layer); Push/Pull/Kill or approve/modify rows actionable by a name; metric shown four ways (PvA/QTD/YTD/FY-LE) where it's a review; ADR/decision logs reviewers leave WITH; reversibility classification; definitions/grain/filters visible on the slide.
+  EXCLUDE: strategic vision / market tours; one-big-number minimalism (that's the exec failure transplanted down); vibes instead of measured costs; hand-waved segments ("engaged users").
+  TEST: plugs straight into the finance/eng model; standalone-readable without a walkthrough.
+  B2. EXPERT-PEER / COMMITTEE / REVIEWER (neurips-oral, phd-thesis/survey-defense, academic-review, humanities/cross-language/divinity seminar, ai-hardtech-pitch to technical partners, fda-510k, research-poster (1m read), erc/nih-nsf/sbir/kakenhi grants)
+  ALTITUDE: claim-cluster / contribution, NOT survey summary. Assumes domain literacy — argues, does not introduce.
+  DENSITY: HIGHEST but cognitive-load-disciplined (one new symbol/claim per slide; one chart per claim with baseline+variable+delta IN the title).
+  INCLUDE: high citation density / full DOIs; original-language or original-symbol stratum load-bearing; benchmark with sample size + date + methodology footnote; failure-mode rates; falsifiable forward bets; every reviewer prior pre-rebutted; contingency per aim; CFR/ISO/Article-precise citations where regulatory.
+  EXCLUDE: lay analogies, "what AI is" definitions, Gartner curves, coverage-over-depth survey, motivational filler. Breadth is the failure; one contribution recalled at lunch is the win.
+
+C. PUBLIC / LEARNER / CONSUMER / LAY
+Three sub-bands:
+  C1. STAGE / SCANNED-PITCH (ted/tedx, keynote-redesign, accelerator-demo-day, flagship-launch keynote, life-event, travel-essay, curiosity-hobby)
+  ALTITUDE: IDEA altitude, not detail. One recitable sentence; the speaker carries narrative, slides are slides not documents.
+  DENSITY: LOWEST. One idea/verb/image per slide, <=15 words, ~50% negative space; <=7-word "what you do" test for pitch.
+  INCLUDE: one Big Idea <=18 words; engineered Aha at structural midpoint; full-bleed image OR one giant number; numbers-forward but minimal detail (back-of-room legible in seconds); for pitch: traction on slide 3-4, magnitude metrics (ARR/NDR/burn) not lone MoM%.
+  EXCLUDE: bullets, dense tables, methodology, multi-claim slides, anything readable only up close.
+  TEST: a stranger recites the one line 24h later.
+  C2. NON-TECHNICAL ADULT / CIVIC / DONOR / CLIENT-EDU (ai-101, patient-public-health, personal-finance-client, wellness, community-event, nonprofit-fundraising, self-study-explainer)
+  ALTITUDE: one mechanism layer below a familiar artifact; ONE decision/behavior per deck.
+  DENSITY: LOW. One key message per slide.
+  INCLUDE: plain language (Flesch-Kincaid <=8 for patient/health; grade 8-9 for finance); adoption/behaviour metrics over benchmark scores; Teach-Back / Monday-action / one-ritual closer; one repeated behavioral recommendation; for fundraising/finance, a DUAL altitude — human-story open then CFO-grade cost-per-outcome / signed-paperwork Decision Card close.
+  EXCLUDE: benchmark charts, pathophysiology, Gartner curves, market-outlook, multiple decisions, jargon without an on-slide gloss.
+  C3. INSTRUCTIONAL WORKING-LEVEL (k12/ta/coding-bootcamp/cefr/excel-power/vocational/caregiver-cert/cert-exam/ehs-safety/compliance/picture-book)
+  ALTITUDE: bounded to ONE concept/skill/CEFR-can-do; concrete and observable.
+  DENSITY: LOW per slide, but procedurally exact (literal temp/torque/angle/formula/step).
+  INCLUDE: I-Do/We-Do/You-Do gradual release with a check every 15 min; worked-example fading (full->partial->problem); break-on-purpose / debug-in-session retrieval; observable pass/fail rubric; for regulated training, on-slide standard tag (42 CFR / NNAAP / OSHA / DOJ-ECCP) so it's BOTH 7am-aide-legible AND auditor-defensible; picture-book = zero exposition, one feeling + 6-12 word caption.
+  EXCLUDE: law-school depth, abstract definitions before a concrete example, coverage of the whole curriculum, marketing pitch tone.
+  TEST: learner reproduces / ships / debugs within 90 seconds, not watches.
+
+==================================================
+AXIS 2 — DELIVERY MODE (presented vs self-read), modulates density only
+==================================================
+
+PRESENTED-LIVE (stage, town-hall, defense talk, oral pitch, lecture, lesson):
+  LOWER density per slide — speaker is the bandwidth. One idea/claim/chart per slide; speaker-note timing; bullets banned at the stage end; slides "disappear into the talk." A self-read-dense slide projected live is the failure (audience reads instead of listening).
+
+SELF-READ / PRE-READ / LEAVE-BEHIND (board pre-read, RFC, rfp-response doc, equity note, investor update, sales-battlecard, qbr pre-read, year-end-review, prd-as-doc):
+  HIGHER density, MUST be standalone-readable — every chart carries its so-what, every title is a conclusion, sources on every slide, navigable in 8 seconds by skim AND defensible on deep read. No reliance on a narrator. Action titles + footnoted sources are mandatory, not optional.
+
+DUAL-MODE (the hardest; many consulting/finance decks): build the skim layer (Minto answer in 2 slides, action titles) ON TOP of an auditable deep layer beneath (dollar-sizing methodology, appendix). Examples: consulting-final-deck (Partner on screen / Director-reviewed PDF), industry-deep-dive (4-min skim + defensible read), incident-postmortem (brutal technical detail internally + plain-English customer summary). Rule: the two layers share one structure; never produce a single MID/MID artifact that serves neither.
+
+AUTO-REFRESH / CADENCE (sql-kpi-weekly, investor-update, lab-meeting): fixed structure cloned for diff-ability; "are you stuck?" / variance answer readable in 90 seconds; on-time and re-runnable beats comprehensive.
+
+==================================================
+THREE QUICK DISAMBIGUATIONS (where decks wrongly converge to MID)
+==================================================
+1. Same metric, different altitude: a board QBR shows ONE variance walk + the ask (high altitude / low density); the operating MOR behind it shows every driver four ways (low altitude / high density). Don't ship the MOR to the board or the QBR to ops.
+2. Expert vs lay on the SAME topic (ai-hardtech-pitch vs ai-101): both about AI — one is eval tables + failure-mode rates for technical partners, the other bans benchmark charts entirely. Audience, not topic, sets altitude.
+3. Pitch is NOT low-detail everywhere: stage demo-day is C1 (one sentence/slide), but the Series B/C IC pre-read is A-altitude self-read (cohort triangles, Rule-of-40, 20-page-memo-equivalent density). Same category, opposite depth — delivery_mode + audience decide.

+# Resolve Image Assets
+
+Use this prompt when a SVGlide deck needs real visual assets. It turns image search and selection into auditable local artifacts. The adapter does not provide an image provider; the agent must use available browsing, search, or local-file capabilities, then write the artifacts below.
+
+## Decision order
+
+1. Read `visual_quality_contract` and slide visual intent.
+2. Decide an `asset_role` for each needed image before searching.
+3. Search candidates with role-specific queries.
+4. Keep selected and rejected candidates in `assets/image_candidates.json`.
+5. Download or copy selected images into `assets/images/`.
+6. Register selected images in `assets/assets_plan.json`, `assets/assets_manifest.json`, and `assets/asset_inventory.json`.
+7. If the deck does not require real images, still write `assets/image_candidates.json` with `requires_real_images=false`, `candidates=[]`, and a concrete `no_image_reason`.
+
+## Role-specific format rules
+
+- `logo`, `transparent_subject`, `floating_product`, `chip_device`: prefer transparent PNG or SVG logo. If the selected asset is JPG/WebP without alpha, write a concrete `format_exception_reason`.
+- `hero_photo`, `scene_photo`, `factory_photo`, `store_photo`, `people_photo`: prefer high-resolution real photography from official or source-traceable pages. Do not prefer PNG solely because it is PNG.
+- `ui_screenshot`, `product_screen`: prefer PNG when available, but reject low-resolution or blurry PNG files.
+- `chart`: use chart tools. Chart SVGs do not count as real image assets.
+
+## Candidate requirements
+
+For entity-driven decks that require real images:
+
+- Keep at least 3 candidates for the cover hero unless the user supplied the only usable image.
+- Keep at least 2 candidates for each important product/person/place/process image role where search is possible.
+- Keep at least one rejected candidate for every searched role unless only one source exists.
+- Prefer official sources first, then press/media sources, then general web sources.
+- Do not use preview wrapper screenshots, generated SVG diagrams, chart SVGs, or tiny logos as real hero photos.
+
+Each candidate must include:
+
+```json
+{
+  "id": "cand-cover-01",
+  "query": "NVIDIA H100 GPU official photo",
+  "source_url": "https://...",
+  "source_class": "official",
+  "format": "jpg",
+  "width": 1600,
+  "height": 900,
+  "has_alpha": false,
+  "asset_role": "hero_photo",
+  "fit_role": "full_bleed",
+  "local_path": "assets/images/nvidia-h100-hero.jpg",
+  "score_bp": 9400,
+  "selected": true,
+  "selection_reason": "official high-resolution product photo; safe for full-bleed crop",
+  "format_exception_reason": "",
+  "rejection_reason": ""
+}
+```
+
+Rejected candidates must keep `selected=false` and explain the reason, for example low resolution, unsafe crop, generic stock look, weak relevance, duplicate image, missing source, or wrong format for role.
+
+## Delivery blockers
+
+Do not finish StageAssets when:
+
+- `requires_real_images=true` but no real selected image candidate exists.
+- Cover image is selected without `fit_role=full_bleed` or `large_ok=true`, unless a concrete selection exception is written.
+- A `transparent_subject`, `floating_product`, `logo`, or `chip_device` selected image is not PNG with alpha or SVG logo and has no concrete `format_exception_reason`.
+- `assets_manifest.json` contains a ready image that has no matching selected candidate or inventory entry.

+## slide_outline
+
+创建大纲 / 项目结构。tool_outline_svg.go.tmpl
+
+```text
+Create the project structure with outline metadata, style settings, and empty slide files.
+
+<instructions>
+- Use this tool AFTER preparing the slide content draft (slide_content.md)
+- The outline defines: page ids, titles, summaries (structural metadata), NOT the detailed content
+- This tool creates: project directory, outline.json, a style file, and empty `.svg` slide placeholders
+- Each slide's actual content will be written later using slides_edit based on the content draft
+- Follow the user's confirmed slide count. If they confirmed a range (e.g., "8-12"), aim for the middle of that range. If no count was specified, default to an 8-12 slide deck. Unless the user explicitly asked for a short / concise deck, never create fewer than 8 slides. Remember that structural slides (cover, agenda, section dividers, closing) consume pages too — factor them into your total so content slides don't get squeezed
+
+For official-site brand decks, preserve the website's visual/content families:
+- factory pages should split major factories or process families when the source exposes them;
+- product pages should use product-line imagery instead of generic material diagrams;
+- shop/retail pages should use store imagery when the source exposes shops;
+- a single "factory matrix" page is insufficient when the source has multiple factory sections and gallery assets.
+
+Visual role assignment:
+- For each slide, assign a `visual_role` in addition to the content role:
+  - `hero_cover`: high-impact first impression, minimal copy, strong image or poster composition
+  - `thesis`: one core judgment, one supporting visual
+  - `evidence_grid`: dense proof page using multiple images, data points, or artifacts
+  - `process_detail`: step or craft page with visible process evidence
+  - `product_compare`: side-by-side visual comparison
+  - `scene_or_retail`: real-world usage or endpoint experience
+- The outline should include at least one high-impact cover and at least one evidence-rich page when the topic has process, craft, product, research, or factual depth.
+- Each slide outline item should include `visual_intent`, explaining how the visual supports the message. Weak intents such as "add a relevant image" are not acceptable. The intent must say what the image proves or clarifies.
+- Each slide outline item should also avoid generic "card grid" as the visual plan unless the user requested a dashboard/report. Name the page-specific visual structure instead: poster cover, route map, annotated photograph, field diagram, image-led comparison, evidence collage, chart page, or closing poster.
+- Across the deck, do not let rounded text panels become the dominant visual rhythm. If several slides need facts or metrics, assign different structures before slides_edit starts.
+
+Layout storyboard assignment:
+- Before finalizing `outline/deck.json`, create a layout storyboard for all slides.
+- Every slide item must include `layout_family`, `layout_archetype`, and `layout_signature`.
+- `layout_archetype` must describe the visible skeleton, not the content topic. Examples: `statement_ledger`, `waterfall_bridge`, `peer_bubble_field`.
+- `layout_signature` must be more specific than the archetype. Examples: `income_statement_horizontal_bar_ledger`, `cash_flow_positive_negative_bridge`, `peer_margin_bubble_field`.
+- For 8-12 slide decks, ensure at least 5 distinct archetypes before calling the outline complete.
+- Do not assign the same archetype to adjacent slides.
+- If the deck is a financial report, do not make every analysis page a chart page. Use a deliberate rhythm such as: `full_bleed_photo_title`, `poster_stat_lockup`, `statement_ledger`, `evidence_collage`, `waterfall_bridge`, `data_scoreboard`, `peer_bubble_field`, `risk_radar`, `closing_poster`.
+</instructions>
+
+<recommended_usage>
+- Use to define the presentation structure and style before writing individual slides
+</recommended_usage>

+把上传 PPTX 导入成可编辑 deck（两协议共用；SVG 下产出 .svg）。tool_convert_pptx.go.tmpl
+
+```text
+Convert and parse a user-uploaded PPTX file to editable .slides format.
+
+This is the ONLY tool for reading/parsing/converting PPTX files. It converts the user's PPTX file into an editable .slides presentation with individual XML files for each slide.
+
+IMPORTANT: NEVER use python-pptx, node-pptx, or write your own script to parse PPTX files. Always use this tool instead.
+
+USE CASES:
+- User wants to edit/modify their existing PPTX presentation
+- User wants to convert PPTX to editable format for manual editing
+- User needs to view their PowerPoint file in the slides editor
+- User wants to read/understand the content of a PPTX file (convert first, then read the XML files)
+- User wants to summarize or analyze a PPTX presentation
+
+WORKFLOW:
+1) Parse the PPTX file and convert to SXSD XML format via RPC
+2) Extract each slide into individual XML files (slide_1.xml, slide_2.xml, etc.)
+3) Create a .slides manifest file for the editor to render
+4) Store converted.xml as reference (hidden file)
+
+INPUT:
+- file_path: path to the PPTX file to convert (must be a .pptx file)
+- directory: sandbox path to store the converted files (e.g., '/home/user/workspace/slides/my_presentation')
+
+OUTPUT:
+- slides_path: absolute path to the .slides manifest file ('{directory}.slides') - use this path for slides_update
+- slide_count: number of slides extracted from the PPTX
+- directory: directory containing individual slide XML files
+
+IMPORTANT:
+- After conversion, use slides_update tool with the slides_path to modify the presentation
+- The original PPTX content is preserved exactly in the converted .slides file
+- If user wants to use PPTX as a STYLE REFERENCE for new slides, use slides_parse_template instead
