/* ============================================
   OpenClaw Game — Felt Style CSS v3.4
   模組：抓娃娃遊戲頁面樣式
   
   依賴：
     - mujoo-tokens.css（Design Token 系統）
     - mujoo-responsive.css（響應式工具類）
   
   原則：
     - 所有數值引用 Token，不寫死
     - 響應式通過 Token 斷點自動適配
     - 結構化、模組化、可維護
   
   CHANGELOG:
     v3.0 - 全面毛毡主題改造
     v3.2 - 修復 crossOrigin CORS mismatch
     v3.3 - 添加三端響應式（硬編碼）
     v3.4 - Token 驅動重構，所有值引用變量
