   配合 assets/ams-shell.js（<ams-shell> / <ams-footer> 自定义元素）：
   页头 · 模块导航 · 移动导航面板 · 外观弹层。所有颜色 / 尺度均取
   assets/ams-theme.css 的语义令牌，不写死 hex。各模块只需：

       <link rel="stylesheet" href="assets/ams-theme.css">
       <link rel="stylesheet" href="assets/ams-shell.css">
       <script src="assets/ams-theme.js"></script>
       <script src="assets/ams-shell.js" defer></script>

   页面里写 <ams-shell mod="overview"></ams-shell> 即可。
