/* ============================================================
   最新消息公告列 .swa —— 心斎ノ翼官網（2026-09-24）
   搭配 /announce.js。資料來源 GET /api/announcements。

   兩種版型（announce.js 依頁面自動判斷）：
   ① 浮動膠囊（overlay）：首頁這種「最上面是大圖 hero」的頁面。膠囊浮在 hero 上方，
      不推擠任何版面 ⇒ CLS＝0；桌機置中、避開左側選單與右上角查空房圓鈕；手機貼在頂部列下方。
   ② 細長橫條（inline）：一般內頁（例如長住區，頁首 sticky:top:0＋.notice-bar）。
      插在 body 最前面、sticky 頁首之前 ⇒ 捲動後頁首照樣貼頂，錨點補償變數不受影響，
      也不會蓋到 .notice-bar。展開時會推擠一次（約 40px）。

   三種樣式：info（一般，墨黑＋金線）／promo（優惠，香檳金）／important（重要，朱紅）。
   🔴 公告文字一律由 JS 用 textContent 放進來，本檔不含任何內容。
