/* ==========================================================================
   《教官你别跑》样式表
   设计思路：
     · 舞台 #stage 固定按 960×640（3:2）设计，再用 transform: scale() 等比铺满屏幕，
       这样画布与所有 DOM 界面（HUD、菜单、结算）始终保持同一套坐标，缩放不会错位；
     · 整体走“军营 / 迷彩 / 黄铜”配色：深蓝夜训底色 + 军绿 + 金币黄；
     · 关键动画：天幕呼吸、金币浮标、体力心跳、挑战进度流光、结算面板弹出。
