/* ============================================================ 7b. 收报（transit）
   打开别人的分享链接时：终端先"抄收"这份记录，抄完才展开全文。

   .transit-hidden 是这套流程里最容易写错的一处（第 3 轮实测纠正）：
   第 2 轮用的是 `visibility: hidden`，以为"看不见但读屏还读得到"。**不成立**——
   Chrome 会把 visibility:hidden 的整棵子树从无障碍树里摘掉（AX 节点 ignored=notVisible），
   于是抄收期间读屏用户和"页内查找"都拿不到这份记录，正好与设计意图相反。
   现在改成 sr-only 那一套（1px + clip-path）：**留在无障碍树里**，读屏与 Ctrl+F 都能读到全文。
   代价是里面的链接与按钮会变成"看不见却 Tab 得到"，所以单独把它们按 visibility 藏掉——
   抄收期间它们本来也不该生效，等展开之后整块恢复。 */
