/* ============================================================
   Joren for LINE — Landing Page
   美容サロン向け LINE 予約/CRM

   設計方針:
   - 和モダン・エディトリアル。上質なサロンのパンフレットの佇まい。
   - 明朝の見出し × ゴシック本文。罫線と余白で構成し、カードの多用を避ける。
   - Joren独自色（墨・生成り・真鍮）が主役。LINE緑は「LINEで動く」文脈にのみ使う。
     全面をLINE緑にすると公式提供と誤認されるため、意図的に抑えている。
