/* ============================================================
   header.css - ヘッダー・ナビゲーション(改修版 2026-05-20)
   --------------------------------------------------------------
   読み込み条件: 全ページで読み込み
   役割:
     - サブページ用ヘッダー(#commonHeader)のスタイル
     - トップ用ヘッダー(#header, .hero__*, #navigation 等)のスタイル
     - CTAボタン(.btn-primary, .btn-secondary)のスタイル

   構成:
     1. 共通スタイル(全デバイス共通)
     2. PC版スタイル(@media min-width: 769px)
     3. スマホ版スタイル(@media max-width: 768px)
     4. その他のメディアクエリ(画面サイズ別の微調整)
     5. アニメーション(@keyframes)

   ルール:
     - font-family / font-size はサイト共通CSS(common.css)で管理
     - 個別フォント指定はアイコン用(FontAwesome等)・装飾用(Roboto等)のみ
     - ブレークポイント: PC ≥ 769px / SP ≤ 768px

   改修ポイント(2026-05-20):
     - ヒーロー背景のオーバーレイを大幅に薄く → 明るく清潔感のある印象に
     - キャッチコピーを黒文字+アクセント色(ピンク/水色)に変更
     - バッジを白背景+黒文字+カラードットに変更
     - CTAボタン(白)を白背景+青枠+黒文字に変更
     - グローバルナビ(PC版)を白背景+アイコン縦並びセンター揃え8項目に
     - スマホ版ナビをフローティング型ハンバーガーメニューに変更
