   色の使い分け
     青緑(--blue) … UI全般。リンク・ボタン・フォーム・選択状態。
     深緑(--green)… 観光・自然のコンテンツ。コース・特産品・レジャー。
     赤(--red)    … 医療・緊急のみ。ほかの用途で使わない。
   画面幅は 900px を境に PC / SP の2通りだけ。中間段は足さず、
   auto-fit と clamp() で連続的に伸ばす。
   命名: 共通部品はフラット短名(.btn .card .tag .sec)、
   ページ固有は短い接頭辞(.dh- .pl- .ev- .of- .mc- .vg-)、状態は .is-*。
   セレクタはブロック直下1段まで。深い子孫セレクタは書かない。 */
