/* ============================================================
   gothic.css — rhyn.jp「大聖堂の夜」共有の土台
   仕様: docs/specs/gothic-redesign.md（3 見た目・4 書体・6 演出の段）

   ここに置くもの（どのページでも同じ）:
     色と書体の変数 / 自前の書体 / 地の文字 / ナビとハンバーガー（js/nav.js と対）/
     節の見出し / ボタン / 金縁の札 / 予定のカード（js/events.js が描く形）/
     薔薇窓 / 印（アイコン）/ 拡大表示 / 足もと / 動き（動きを減らす設定では出さない）
   ページだけの配置は各ページの <style> に置く。

   ■ 書体の決まり
     - 日本語は端末の明朝（ウェブ書体として読まない）
     - 名前「Rhyn」は 'Rhyn Name'（Grenze Gotisch を R h y n の4字に絞ったもの。preload する）
     - 見出しの欧文は Grenze Gotisch、小さな見出し・日付の欧文は Cormorant Garamond。
       どちらも、ページに出る欧文の字だけに絞って fonts/ に置いている
     - Cinzel / Cinzel Decorative（大文字しか無い）は使わない。名前が RHYN に見えるため

   ■ 動きの決まり
     - 何も動かなくても完成して見える（段1）
     - 動き（薔薇窓の回転・金の光沢・ろうそくの揺らぎ・火の粉・hover の変化）は
       すべて @media (prefers-reduced-motion: no-preference) の中で、transform と opacity だけを動かす
     - 出現の動きで中身を隠さない（読み込んだ瞬間から全部読める）
