   第 4 章 · 名单阶段磨砂玻璃（★ 全站唯一一份定义，别再在别处叠加任何 #ch4Dim 规则）

   需求：名单升起来的瞬间，整个背景变磨砂玻璃（灰 + 模糊），把此前演过的
        外号卡片 / 外号墙全部盖住，名单本身浮在最上面清晰可见。
   层级（都是 #stage 这个 z-index:10 层叠上下文里的比较，见 base.css 的 .chapter-root）：
        旧内容 .ch4-card / .ch4-wall / .ch4-spot ... 默认(auto)
        磨砂层 #ch4Dim ............................. 30
        名单框 .ch4-rb / [data-rb] ................. 40
   重要：#ch4Dim 由 ch4.js 的 dimEl() 插在 .ch4-wrap 内部（position:fixed 铺满视口）。
        绝不能挂到 body 上 —— .ch4-wrap 自己有整屏不透明渐变底，#stage 又是
        z-index:10 的层叠上下文，body 上的遮罩永远被压在后面看不见。
