"""
生成 App 的双色图标集（SVG）。

为什么要有这个脚本：
  图标是「设计系统」的一部分，不是一堆散文件。把形状和配色集中写在这里，
  改动（换圆角、调粗细、换某个颜色的深浅）只需要改一个地方再重跑，
  不用手工去改 30 个 SVG。

设计规范：
  · 画布 24×24，内容控制在 3~21 之间留出视觉边距
  · 线条粗细统一 2.0，端点和连接处全部圆角（这是「可爱」的关键）
  · 双色：浅色填充 + 深色描边（类似 Phosphor Duotone 的做法）
  · 配色以品牌焦糖色 #C8956E 为锚，压低饱和度，保证整体暖调统一

产物：
  assets/icons/<name>.svg                    提交进仓库，由 flutter_svg 渲染
  <后台>/static/admin/icons/<name>.svg        同一套图标给网页后台用
  <后台>/static/admin/icons.js                图标名清单 + emoji 兼容映射
  tools/_icons_preview.html                   预览页（浏览器打开检查，不提交）

用法：
  python tools/make_icons.py                 # 只生成 App 的图标
  python tools/make_icons.py --preview       # 额外生成预览页
  python tools/make_icons.py --sync-web      # 同时同步给网页后台（改了图标就带上）
