/* ============================================================
   総合TOP 案1「シャンパンの夜」(2026-07-28承認・本番TOPの正本CSS)
   利用箇所: /(本番TOP) と /top-preview(確認用・noindex) の2ルート。
   夜にコミットした単一テーマ(ライト/ダーク切替なし・意図的)。
   色はロゴ実測 #FDBDBC ＋ サイト共通CSSの実在ピンクのみで構成。
   動きは transform/opacity のみ(GPU合成・低負荷)。JSは一切使わない。
   ★prefers-reduced-motion では止めない(澤口さん指示・2026-07-28)。
     iPhoneの「視差効果を減らす」ON環境でも泡・光・マーキーを動かす。
     動きは全て低速・小振幅で、点滅・大きな視差は含まないため許容と判断。
