   無料ユーザー向けプロモ表示（Phase 1）のスタイル。
   (1) 紙芝居オーバーレイ .storyboard-*
       - writing/index.html の該当 CSS をそのままコピー（クラス名統一で流用）。
         writing 側にも残しているため、どちらから呼んでも同じ見た目になる。
   (2) カードタップ時のプロモモーダル .promo-modal-*
       - play.html の _showRoomLockedHint を雛形に、スクショ表示用モーダル。
   z-index 棲み分け: storyboard=10010, promo-modal=9999,
                    #pono-return-greet=9998, _room-locked-hint=99999 (既存)
