/* ── 16. 导航条修复 ─────────────────────────────────────────
   两个毛病，都不是质感层引入的，从初版就在：

   1) 顶栏吸顶失效。.page-shell 用了 overflow: hidden，祖先一旦成为
      滚动容器，后代的 position: sticky 就失去参照，跟着页面一起滚走。
      改用 overflow-x: clip —— 同样能裁掉横向溢出，但不会创建滚动容器，
      sticky 得以保留。（overflow-x: hidden 不行，它会把 overflow-y
      隐式算成 auto，照样破坏 sticky。）

   2) 窄屏没有导航。原规则在 ≤1020px 直接 display:none 把导航整条藏掉，
      ≤某宽度连 CTA 也藏。这个页面接近 27000px 高，手机上没有导航
      等于只能一路滚到底。改成横向可滑的一行，CTA 保留。
