 ## 状态与路由
 
-应用启动先请求 `system/status`，已初始化时再请求 `auth/me`。未初始化渲染安装页；未登录渲染登录页；登录后由 `BrowserRouter` 提供 `/` 总览和 `/settings` 设置，未知路径回到 `/`。状态响应中的构建版本以 `v<version>` 徽标显示在安装页、登录页和登录后侧栏的品牌区域。这些分支只负责交互，服务端 session 才是安全边界。
+应用启动先请求 `system/status`，已初始化时再请求 `auth/me`。未初始化渲染安装页；未登录渲染登录页；登录后由 `BrowserRouter` 提供 `/` 总览和 `/settings` 设置，未知路径回到 `/`。状态响应中的构建版本以 `v<version>` 徽标显示在安装页、登录页和登录后侧栏的品牌区域；品牌图标、名称和版本徽标保持单行排列。这些分支只负责交互，服务端 session 才是安全边界。
 
 主题以服务端通用设置为持久来源，`localStorage` 仅用于首屏缓存；system 模式会跟随系统主题变化。当前账号 ID 保存到 `localStorage`。总览先加载账号列表，为当前账号加载 Dashboard，并在每轮请求完成 30 秒后刷新；切换账号会取消旧请求并校验响应账号，避免迟到响应覆盖当前账号。手动刷新调用账号级 sync 后重新读取 Dashboard。
