/* ============================================================
   CueSync LP
   アプリ本体（src/app/globals.css）と同じデザイントークンを使う。
   LPとアプリで世界観を切らないため、色・タイポの定義はここに複製する。
   ※ アプリ側のトークンを変えたら、ここも合わせて更新すること。

   デザインの方針:
   - 舞台の暗転がベース。光は「差す」ものとして扱い、面で塗らない。
   - 数値・タイムコード・ラベルは等幅。現場の道具としての精度感を出す。
   - 実際のアプリ画面を主役に置き、装飾はその周りを照らすだけに留める。
