   法之道 · 骨架屏（Skeleton）v1.0
   ───────────────────────────────────────────────────────────────────────
   解决两件事（田总原话：「每次从一个页面切换到另一个页面的时候不要一闪
   一闪的加载数据，要做骨架屏，内容没加载完先显示灰色占位块」）：
     ① 跨页跳转：新页面第一帧就是灰底 + 骨架，不出现白屏
     ② 数据未到：主内容区显示灰色占位块，数据到达后淡出，页面不跳动

   结构全部是【加法】：
     - 骨架层是独立 fixed 容器，不写进业务 DOM，业务代码 innerHTML 覆盖
       也带不走它；移除时只删自己这一个节点
     - 删除本文件引用 + ui-skeleton.js 引用即完全回滚
   ⚠️ 本文件不含任何 !important 业务覆盖，只影响 .sk-* 命名空间。
