   - 閉じている時:  .leaflet-tab               右側に常駐するタッチタブ
   - 開いている時:  .leaflet-overlay / -panel  右からスライドインする全画面パネル

   デザイン方針:
   - タブは「温度・時計」と同じグラスモーフィズム (box-blur) をベースに、
     78thテーマカラー(--red)のアクセントを効かせて視認性を確保
   - 定期的に "ぴょこぴょこ" と横揺れして目を引くアニメーションを付与
   - パネルは最前面 (z-index: 2000) で右から 92vw スライドイン
   - サイネージ向けに全体を大きめのタッチターゲットにし、視認性第一のレイアウト
