/* 首頁 hero「每家長自己的樣子」（Frank 2026-10-01 選定的方向 A）。
   動態只做一件事：證明產品的差異（每家俱樂部長得不一樣）。
   顏色逐字取自 services/clubPage/templates.ts 三套版型：
     雜誌敘事（竹光）  background #FBF8F3  accent #B0543A
     夜場節奏（大安）  background #101110  accent #d5ff70
     球場能量（板橋）  background #F2EFE7  accent #16281F／照片上 #9FE870
   只動 opacity／transform；切換＝疊著的圖層換 opacity，不動 background-color。 */
