/* ================================================================
   小鎮飲料戰 Little Town — 樣式
   ----------------------------------------------------------------
   設計原則：
   1. 可投影 —— 帶領人控台的字級刻意放大，後排也看得到
   2. 手機可用 —— 學員可能用手機提交，760px 以下全部改單欄
   3. 五組各有代表色 —— 色碼與 web_server.py 的 TEAM_PRESETS 對齊
   4. 零外部資源 —— 不引入任何字型 CDN，只用系統既有的中文字型
