/* ============================================================
   整体院LP テンプレート v3（画像強化版）
   設計方針（04_Web作成ガイドより）
   - 配色は ベース70% / メイン25% / アクセント5% の3色構成
   - 本文16px以上、見出しはclampによる流動的サイズ
   - コントラスト比 4.5:1 以上（WCAG準拠）
   - 余白を多めに取り、近接・整列・反復・対比の4原則を意識
   - レスポンシブ＋フルイドデザイン（clamp / minmax）
   - アクセシビリティ（focus-visible, aria, reduced-motion）
   ============================================================ */
