 Uses **React Router v7** (`react-router`) with `createBrowserRouter`.
 
-- Route config lives in `src/router.tsx`
-- `RootLayout` wraps all routes — add shared nav/header/footer there
-- Add new pages under `src/pages/`, register them in `src/router.tsx`
+- **唯一数据源**：`src/routes/index.tsx` 维护 `routes: RouteItem[]` 路由树
+- `RouteItem` 字段：`path` / `label` / `icon?` / `component?` / `hideInMenu?` / `redirect?` / `children?`
+- `toRouteObjects(routes)` 将路由树转换为 React Router 所需的 `RouteObject[]`
+- 菜单、面包屑等模块直接消费 `routes` 数组，无需重复维护路由信息
+- 添加新页面：在 `src/pages/` 创建组件，在 `src/routes/index.tsx` 追加节点即可
