# Design QA — 食用手册应用图标

- Date: 2026-08-17
- Visual target: Product Design ideation option 2
- Surfaces: Web/PWA, iOS launcher, Android launcher, YunLeFun native authorization sheet

## Visual fidelity

- Preserved the selected top-down pot composition, emerald background, cream vessel, and green/red/gold ingredients.
- Flattened incidental raster shading into five stable brand colors without changing the silhouette or hierarchy.
- Produced a transparent `cook-mark` and a full-square `cook-app-icon` from the same selected artwork.
- Shifted the foreground down 16 units on the 1254-unit canvas so its measured vertical bounds are centered at 626.5.
- Enlarged and regularized both handle openings so they stay legible at launcher sizes.
- Replaced the traced inner rim with a cleaner 30-unit circular stroke.
- Consolidated the two white highlights into one stronger four-point tomato highlight.

## Platform checks

- 16, 24, 32, and 64 px previews keep the pot and three ingredient groups distinguishable.
- The full-square source has no precomposed corner mask or shadow; iOS and Android apply their own masks.
- iOS Simulator shows the installed name as “食用手册” and the new launcher icon without clipping.
- The YunLeFun authorization sheet renders the same PNG at 64 pt without overlap, fallback text, or transparency artifacts.
- Web/PWA and iOS PNGs are opaque; the Android adaptive foreground retains transparency over the emerald background layer.

## Build gates

- Cook lint, typecheck, targeted authentication tests, icon metadata tests, and static production build passed.
- Android `assembleDebug` passed with the local OpenJDK 21 runtime.
- YunLeFun/icons build, tests, lint, typecheck, docs build, and package dry run passed.

final result: passed
