/* ---------------- 首屏占位：预留高度，防 CLS（布局抖动） ----------------
   index.html 的活动 / 公告 / 节目单 / 聊天室都是「先占位、后异步填充」。占位块若比
   真实内容矮，数据到达时区块被撑高，就会把下方元素整体顶下去。解决办法是给容器预留
   min-height（约等于一条真实内容的高度），让「加载中」和「加载完成」两态高度一致：
   内容到达时只做原地替换，下方元素不动，CLS 趋近 0。
   数值随断点变化（卡片内边距、聊天记录区高度在移动端更小），故用变量统一维护，
   移动端在下方 @media (max-width: 767px) 里覆盖。
   注意：预留高度只在「内容不超过它」时才算无抖动；列表条数由数据决定，这里按
   「一条卡片 + 可能出现的『查看全部』按钮」取值。条数更多时列表会在末尾向下增长，
   但那不会把首屏已有的元素顶出视口。 */
