/* ==================================================================
   ライトプランの制作例②（架空のネイルサロン）専用スタイルシート
   ==================================================================
   「Y2K・ポップ」なテイストに全振りしたデザインです。制作例①（美容
   クリニック）・制作例③（カフェ）とは配色もフォントも別物にして
   あります。グラデーションの背景、コラージュ風に重ねたポラロイド
   カード、無限スクロールのマーキー帯、丸文字フォントなど、若い
   客層に刺さる賑やかな世界観を意図的に作っています。
