/* ============================================================
   footer-v2.css — 全站頁尾(main.master <footer>）v2 改版專用
   - 獨立元件,所有 class 加 iv2-foot 前綴,scope 在 .iv2-foot 內
   - 風格:淺色頁尾(off-white 漸層底 + 深字 + 紫→琥珀漸層頂線 + 微光氛圍),與白色導覽列同調
   - 分班據點以可點擊地圖卡片呈現;字體沿用 iv2 設計系統 Noto Sans TC
   - em 為主(scope 內 font-size 為 em 基準）;標點:程式半形、文案全形
   - 覆蓋 style.css 既有 footer/footer p/footer a 標籤選擇器(以 .iv2-foot 提高 specificity）
   - 2026-05-23 建立;同日改為淺色主題
