/* ==========================================================================
   ai-video-production.html — THE INVISIBLE STUDIO 専用スタイル

   デザイン言語: 映画館の文法（レターボックス / タイムコード / フィルムストリップ）
   色: 黒 #080808 × ブランド赤 #E63946。赤の発光は面積を絞って使う。

   構成:
     1. 共通CSSの打ち消し（sticky/pin を殺す overflow-x, SP の word-break）
     2. 共通パーツ（スレート表記・見出しの折り返し固定）
     3. ヒーロー  … 連番スクラブ（pin）＋レターボックス＋撮影機材UI
     4. PROOF     … 画面幅いっぱいの宣言文（読点単位の段階着色）
     5. DECK      … 用途6種の 3D カード（組み上がり＋ホバー微傾斜）
     6. REASONS   … エディトリアルな索引レイアウト
     7. FLOW      … フィルムストリップ（pin・横送り）
     8. PRICING / FAQ / CTA
     9. リビール・pin スペーサー
    10. レスポンシブ / reduced-motion

   .js が付いているときだけ演出用のレイアウト（pin 区間・初期非表示）を当てる。
   GSAP が CDN から来なかった場合は .js が外れ、全セクションが素の縦並びで読める。
