/* ============================================================
   フタリゴト 紹介サイト
   アプリ本体（mobile/）のデザイン v2 と同じ色を使う。
   色を変えるときは mobile/tailwind.config.js と揃えること。

   このサイトの狙い（v2 / 2026-09-01 改訂）:
   ・見出しは明朝体。毎日ひとことを書き合うアプリなので、手紙・日記の温度を出す。
   ・背景は一様な灰色にせず、コーラルとブルーの淡い光をセクションごとに移す。
   ・「相互開示」だけは画面いっぱいの暗い面にして、流れに緩急をつける。
   ・全面に極薄の紙目を敷き、CSS で作った平坦さを消す。
