   原写法 `.nav-item-has-mega:hover .mega4` 有两个致命问题：

   ② 更狠的是 —— .mega4 本身是 .nav-item-has-mega 的后代，
      面板宽 1000px 居中定位（x=-88~912, y=55~518），
      这块【大矩形即使 opacity:0 也照样参与命中】→ 鼠标移到 Products
      下方老远的空白处，hover 也成立 → 面板莫名其妙弹开。
      实测：未展开状态下鼠标移到 (200,300)（面板本该在的空白位）→ op 立刻变 1。
   修法：展开完全交给 JS 的 .mega-hover / .mega-open 类（可加延迟），
      并把触碰判定收窄到【只看触发链接 .nav-link 本体】，
      面板只负责"进去后维持不收起"（.mega4:hover 时保持）。 */
