 - 历史会话存后端（`chat_session` / `chat_message` 两张表），App 只发 `sessionId + content`。**工具调用的中间过程不入库**，所以 App 不用理解 tool 消息格式。
 - 助手气泡用 `MarkdownBody` 渲染（回答里常有列表/代码块），用户气泡用 `SelectableText`。
 - 后端未配 key 时不报错：`/api/ai/status` 返回 `enabled:false`，`/chat` 推一个 error 事件，页面顶部显示红色提示条。
 - **AI 写库后必须让 App 侧的数据失效**（2026-09-24 修的真实 bug）。`AssistantNotifier.send` 里跟踪 SSE 的 `tool` 事件，命中 `_mutatingTools`（`create_bill` / `create_note`）就在对话结束后调 `invalidateBillData(ref)` 或失效那四个笔记 provider。
  **为什么必须显式做**：`IndexedStack` 让首页仪表盘和「我的」页常驻，它们 watch 的 `monthlyStatisticsProvider` / `budgetProvider` / `accountProvider` **永远不会被 autoDispose 回收**，只靠「写操作后显式失效」更新。AI 是在服务端直接写库的，App 不知情 → 这三个一直是旧数。而 `billsProvider` 只被 push 出来的记账首页 watch，会被回收重取 —— 于是现象是**「账单列表对了、汇总和预算环没对」**，很有迷惑性。
  回归测试在 `test/ai_refresh_test.dart`（用假 AiApi 吐 SSE 事件，断言 provider 的重建次数）。**加新的写工具时记得同步 `_mutatingTools`**，否则会静默失效。
 ## 设计规范（配色）
 - 品牌主色：`#C8956E`（驼色/焦糖色），在 `app.dart` 中作为 `ColorScheme.fromSeed` 的 seedColor。

 """
 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）
