/* #889 2026-09-30 Vega：手機橫向溢出修正（Genspark 原站就有：390 寬內容撐到 466）。
   原因：兩欄用 1fr，欄的最小寬度＝卡片內容寬（40px 大字＋左右 26px 內距），兩欄加起來超過螢幕。
   改法：欄寬允許縮到 0、手機上內距與字級收小。只在 640px 以下生效，桌機不變。 */

/* #889 2026-09-30 Vega：手機頂端三個問題（Joey 9/30 00:16 iPhone 截圖）。
   ① body 開頭有一個孤立的 Font Awesome 私有字碼（U+F0DD，拿掉公告列時殘留）→ 已從 index.html 刪掉；
      它顯示成缺字方塊，還把 hero 往下推 28px，露出一條白底。
   ② 手機選單關著時只是往上推一整個螢幕高，底邊貼著 y=0；裡面那顆預約按鈕的光圈與陰影會漏到畫面頂端
      → 關著時 visibility:hidden，等往上收的動畫播完才藏（0.5s），開啟時立刻出現。
   ③ 首屏主按鈕的放大脈動（scale 1.06）與往外擴的光圈（scale 1.5）在滿版按鈕上會超出內容欄
      → 手機上改成只有陰影呼吸，兩顆按鈕同寬對齊。桌機效果不變。 */
