/* =========================================================================
   カフェテンプレート スタイル(古民家カフェ / ナチュラル)
   配色の切り替えは下の :root 変数を差し替えるだけ(README「配色の切り替え」)。
   変数名・クラス名は他テンプレート(restaurant/juku/dojo)と共通化してあり、
   .faq-* / .form-note / .float-cta などのブロックは相互にコピーできる。
   デザイン原則:
   - 明色アクセント(テラコッタ)を白背景に器(丸・帯)として置かない。
     濃色(深緑)の上の小さなマーク・細い線としてのみ使う(CLAUDE.md の鉄則を準用)
   - 見出しは Zen Old Mincho。明朝は行ボックスが膨張するため line-height を明示する
