-## 文件说明
-
-| 文件 | 用途 | 尺寸 | 格式 |
-|------|------|------|------|
-| `icon.svg` | 源图标 | 64x64 | SVG |
-| `icon.png` | 托盘图标 | 64x64 | PNG |
-| `AppIcon.icns` | macOS 应用图标 | 多尺寸 | ICNS |
-| `icon.ico` | Windows 应用图标 | 256x256 | ICO |
-
-## 替换图标
-
-### 1. 准备图标
-
-推荐使用 SVG 格式的源图标，尺寸至少 256x256。
-
-### 2. 生成各平台图标
-
-**托盘图标 (PNG)**：
-```bash
-magick your-icon.svg -resize 64x64 icon.png
-```
-
-**macOS 应用图标 (ICNS)**：
-```bash
-mkdir icon.iconset
-magick your-icon.svg -resize 16x16 icon.iconset/icon_16x16.png
-magick your-icon.svg -resize 32x32 icon.iconset/icon_16x16@2x.png
-magick your-icon.svg -resize 32x32 icon.iconset/icon_32x32.png
-magick your-icon.svg -resize 64x64 icon.iconset/icon_32x32@2x.png
-magick your-icon.svg -resize 128x128 icon.iconset/icon_128x128.png
-magick your-icon.svg -resize 256x256 icon.iconset/icon_128x128@2x.png
-iconutil -c icns icon.iconset -o AppIcon.icns
-rm -rf icon.iconset
-```
-
-**Windows 应用图标 (ICO)**：
-```bash
-magick your-icon.svg -resize 256x256 icon.ico
-```
-
-### 3. 替换文件
-
-将生成的文件放入此目录，然后重新构建桌面应用：
-```bash
-./scripts/build/build-darwin-arm64.sh
-```
-
-## macOS Template 图标
-
-macOS 支持 Template 图标，自动适配深浅色模式：
-- 使用黑色 + 透明设计
-- 文件名以 `Template` 结尾（如 `iconTemplate.png`）
-- 黑色在深色模式下自动变为白色
-
-## 设计建议
-
-- 托盘图标应简洁，在小尺寸下清晰可辨
-- 避免过多细节和文字
-- 使用高对比度颜色
-- macOS 建议使用 Template 图标风格
