/* ============================================================
   amane — "渚と白光" (Nagisa & Hakkō)
   内房オーシャンフロントヴィラのためのデザインシステム。

   設計の軸:
   - 和風装飾を持たない。amaneは旅館ではなくフリースタイルのヴィラ。
     「墨と生成」(honkan/bettei/hiruta) の和のボキャブラリは使わない。
   - 白光（west-facing の逆光）を主役に、砂 → 白 → 藍のグラデーション。
     差し色は内海の藍 (--sea) と夕陽 (--sun) の2色のみ。
   - 直線と余白。角丸ゼロ、影は最小限、罫は 1px の hairline。
   - 横一文字の水平線ルール（.rule）がサイト全体の通奏低音。
