/* =============================================
   🔮 命運抽卡 (Fortune Draw)
   詳細設計見 docs/fortune_draw.md
   配色一律使用 root 變數，自動相容 light/dark mode：
     --card-bg / --bg-color / --text-main / --text-sub
     --accent-color / --border-color
   原則：不使用 linear-gradient / radial-gradient、
         不使用 box-shadow / text-shadow、不使用 backdrop-filter blur
