/* =========================
  Ikeuchi_KM LP - style.css (refactored)
  変更メモ:
  - 値は維持したまま、重複ルールを統合してセクション整理（Base/Tokens/Layout/Components/Media queries）
  - .btn / .btn--primary / .btn--ghost を変数中心に再編（::before内枠 / ::after右下三角は維持）
  - 分散していた同一条件の media query を集約（最終カスケード結果は維持）

  検証チェックリスト（変更前/変更後スクショ比較: 375/640/768/1024/1200px）:
  [ ] FV（背景画像・見出し位置・CTA幅）
  [ ] problem（背景ポリゴン・チェックリスト・proofカード）
  [ ] features（画像背面色面・テキスト面・ghostボタン）
  [ ] doctor（2カラム→1カラム遷移・画像幅）
  [ ] flow（縦ライン接続・番号丸）
  [ ] faq（開閉アイコン向き・余白）
  [ ] contact（フォーム2→1カラム・入力高さ）
  [ ] footer（グリッド崩れ・情報行）
  [ ] sticky-cta（表示/非表示・body下余白）
  [ ] ボタン（.btn::before内枠 / .btn::after三角 / hover挙動）
