  /* v19 修复（2026-05-18）：苏总反馈所有页面安卓还是滑不动
     根因：
       1) `html` + `body` 同时 overflow-x:hidden + max-width:100vw，
          会让安卓 Chromium / 鸿蒙 / 华为 / MIUI 内核找不到「真正可滚动的根」，
          于是两个都不滚，整页死锁。
       2) html 上的 overflow-x:hidden 在 Android WebView 经常等价于把 vertical
          scroll 一起干掉。
     修法：
       - 不再在 html 上设 overflow / max-width，把横向溢出兜底只放在 body 上；
       - 保留 -webkit-overflow-scrolling: touch（iOS only，不影响安卓）；
       - 保留 min-height: 100% 兜底（鸿蒙 100vh 异常）。 */
