   产品介绍与使用教程（/tour）
   ----------------------------------------------------------------------------
   这是一个**独立的全屏演示页**：整页只有它自己的舞台，不复用后台外壳
   （页面 meta 里 layout: 'auth' + bare: true 会让外壳进入 is-bare 状态）。

   设计基调：与系统内其它页面**同一套设计语言**（颜色、圆角、阴影、动效全部取 tokens），
   但允许更「舞台化」：更深的背景、更大的标题、更明显的强调色。

   分节（实现时按此顺序追加，不要重排既有分节编号）：
     1. 舞台与背景               .tour / .tour__bg / .tour__glow
     2. 顶部标题栏与品牌         .tour-top / .tour-brand
     3. 播放器控件               .tour-controls / .tour-progress / .tour-speed
     4. 章节轨道与角色切换       .tour-chapters / .tour-role
     5. 假窗口（浏览器/应用框）   .tour-window / .tour-window__bar / .tour-window__body
     6. 复刻的后台界面           .tour-app / .tour-app__nav / .tour-app__main
     7. 复刻的学生端界面         .tour-stu-*
     8. 复刻的大屏界面           .tour-kiosk-*（毛玻璃卡片）
     9. 光标 / 高亮 / 波纹 / 字幕 .tour-cursor / .tour-spot / .tour-ripple / .tour-caption
    10. 结尾页与页脚             .tour-end / .tour-foot
    11. 响应式与减动效           @media / prefers-reduced-motion

   约定：
     · 假窗口**内部**刻意复用真实页面的类名（card / stat-card / badge / btn / tabs /
       table / timeline / toast / alert / empty-state / chip / avatar / score-pill /
       activity-item / rank-chip / field / input / switch…），这样复刻出来的界面
       和真系统长得一模一样；
     · 假窗口**外**（舞台、播放器、光标、字幕）一律用 .tour-* / .tour__* 前缀，
       不污染真实页面；
     · 3D 感全部用 CSS 3D（perspective / preserve-3d / rotateX），背景星点用 Canvas 2D，
       不引入任何外部资源。

   早期版本做成"静止 3 秒淡出"，已按需求改为**常驻不隐藏**（`.is-visible` 一直保留）。
   dock 相对视口定位的前提是祖先不带 transform——见本文件顶部 `.tour` 的说明。
   假窗口的底部安全间距在 `.tour-stage` 的 padding-bottom 上预留（--tour-float-space）。
