   レイアウトと部品の「骨格」はここに置き、a.css / b.css は色・書体・案ごとの差分だけを持つ。

   テーマ側で定義するトークン
     色   : --c-bg / --c-bg2 / --c-fg / --c-fg2 / --c-line / --c-accent / --c-on-accent / --c-focus
     書体 : --f-serif / --f-sans / --f-en
     幅   : --w-max

   クラス名の対応（短い名前はよく使う部品だけ）
     .hd ヘッダー / .kv ファーストビュー / .ph 画像の枠 / .rv スクロールで現れる要素
     .ttl セクション見出し / .sty お品書きのスタイル（単品・食べ飲み放題）/ .fix 固定ボタン / .ft フッター
