/* 顶栏走 fixed + 等高占位块（.hd-space），不走 sticky。
   原因：sticky 的顶栏在文档流里，吸顶时 .header-inner 从 --hd-h 收到
   --hd-h-stuck（76->64 / 80->66 / 84->68 / 88->70），整篇文档高度随之变化，
   正文被整体挪动 12~18px；浏览器的 scroll anchoring 会把 pageYOffset 回写同样的
   位移，于是 is-stuck 在阈值附近被自己反复触发 -> 顶栏来回抖。
   改成 fixed 后收缩只发生在 fixed 层，文档流零变化，阈值不可能被自己触发。 */
