   YouRairo 公式サイト トップページ v5「CHAPTER CITY」テーマ（新規）
   - v4.x「GRAPH PAPER STUDIO」のテーマCSS（theme-graphpaper.css／scroll-effects.css）と、v08 の style.css は読み込まない。
     レイアウト・部品の見た目はこのファイルで一から書く。デモ作品の画面の見た目だけは v5-works.css へ移植（変更なし）。
   - 章ごとの全画面の色（テイクオーバー）は v5-motion.css＋js/v5-scroll-engine.js。
     JSなし・動きを減らす設定では、各章がその章の色（--v5-k）の平らな背景で完成した状態のまま表示される。
   - グラデーションは使わない。本文・料金・リンクは必ず白い不透明のカード／パネルの上に置く。
