/* 收合/展開動畫 (規格書未涵蓋，本次擴充新增)：用「grid-template-rows: 1fr → 0fr」取代 display:none，
   這是目前 CSS 動畫 auto 高度最主流的做法 — 不需要 JS 量測 scrollHeight，Grid 的 fr 單位可以直接被
   瀏覽器補間動畫。.zone-body 是 injectTileHandles() 在 JS 裡動態包起來的外層；.zone-grid 需要
   overflow:hidden 才會在收合時被真的裁掉而不是內容溢出，因此 .tile-resize-handle 改成完全收在
   面板自己的邊框內（不再往外凸出），才不會被這裡的 overflow:hidden 切掉一截。
   實測發現：這個 fr 值如果是「換一條 class 規則」改變的（例如 .zone.collapsed .zone-body{...}），
   在部分瀏覽器組合下完全不會補間、直接跳到終值；但改成 JS 直接寫 inline style（見
   owner-view.js:renderZoneLayout）就會正常動畫，所以這裡只留 transition 宣告，實際數值交給 JS 控制。 */
