The macOS source icon's squircle was full-bleed — its artwork filled the entire 1024×1024 canvas edge-to-edge (alpha bbox = 0,0,1024,1024). macOS renders the app-bundle icon as-is in the Dock and Launchpad, so a full-bleed mark reads optically larger than neighboring apps whose icon body sits inside the standard safe area, which is the "oversized icon" reported in #1751. Re-composite the artwork to the Apple macOS app-icon template body size — 824×824 centered in 1024×1024 (≈80.5% occupancy, 100 px margin per side per the HIG) — and rebuild icon.icns from the padded master (full 16→1024 @1x/@2x size set). Scoped to the macOS packaging assets: tools/pack/resources/mac/icon.{png,icns}. The web app-icon.svg/png stay full-bleed (web icons aren't slotted/masked like the Dock), and linux/win assets are out of scope for this macOS-only report. icon.icns is the asset electron-builder actually ships (mac.icon + dmg.icon in tools/pack/src/mac/builder.ts); icon.png is the source-of-truth and is updated to match. The .icns is assembled directly from oxipng-optimized PNG entries (not via iconutil, which re-encodes and produced a 1.12 MB blob that tripped the 1 MiB changed-file guard). Hand-packing the standard icns type set (icp4/icp5/ic07–ic14) keeps it lossless at 731 KB, comfortably under the guard. Verified valid: `iconutil -c iconset` round-trips it back to all 10 sizes, and the 1024 representation retains the 824×824 padded bbox.
