/* しまかげ柑橘舎（架空のお店）— 制作見本7：食品通販のトップ・商品一覧・商品詳細
   配色は2案（?theme=a ／ ?theme=b で全ページ切り替え）。決め方は research.md。
   - A案「みかん畑」＝白地＋生成りの面＋深い緑の文字アクセント。カートのボタンは柑橘の橙
   - B案「島の海」 ＝白地＋淡い青磁の面＋深い青緑のアクセント。カートのボタンは同じく橙
   どちらも、実物 8店中5店がカートのボタンを暖色（橙・赤・山吹）にしていた所に合わせた。
   文字の大きさは全部 16px 以上（価格の注記・バッジ・フッターも）。コントラスト比は check.py で実測。 */
