/* ===================================
   Chainlytic×AI - Main Stylesheet
   Safe Organized Edition / main.css

   【この版でやったこと】
   - デザインを壊さないため、セレクタ本体は基本そのまま維持
   - コメントと区切りを整理
   - 後半に追加されていた Contact / FAQ / Contact Modal の整理ブロックを
     「Refactor Additions」として明示
   - 削除はせず、既存のカスケード順を極力維持

   【この版でまだやっていないこと】
   - 色・余白・サイズの微調整
   - 大規模なセレクタ統合
   - レイアウト変更
   - 不要CSSの削除

   【方針メモ】
   - 今回は “壊さない並び整理” を優先
   - 見た目に影響しやすい順序変更は避ける
   - 既存の後勝ちルールを守るため、追記ブロックは後半に保持
