  /* 横向溢出兜底。只用 clip，不再声明 hidden 兜旧浏览器，理由：
     1) 移动端的溢出根因（.reveal-pending 的 translateX）已在 ≤960px 改为纵向入场，
        实测 320/360/390/414/768/960px 下即使完全移除本兜底，scrollWidth 也等于
        clientWidth——窄屏已经没有需要遮的东西了；
     2) overflow-x: hidden 会让 overflow-y 计算值变成 auto，把 html 变成滚动容器，
        这正是 iOS ≤15 上破坏 sticky / 惯性滚动的已知来源。而这条兜底偏偏只在
        那些老浏览器上生效——风险全留下，收益是零；
     3) clip 在老浏览器里是无效值会被直接丢弃，等于它们回到完全默认的行为。
     ≥961px 桌面端仍有约 40px 横移溢出（版面够宽，横向入场保留），由 clip 接住。
     body 上的 clip 不会传播到视口，所以 html 这一层必须保留。 */
