/* ==========================================================================
   app.css — 群组游戏中心 MiniApp 手绘样式
   设计基调：深夜棋室。墨绿黑呢绒台面、黄铜描边、暖纸白字、木质棋盘。
   反 AI 味约定：
   - 禁止紫蓝渐变；主色只用墨绿/炭黑/黄铜/暖白，棋子棋盘用 CSS 几何绘制；
   - 卡片不用模板化白卡堆叠，用发丝线 + 暗纹区分层级；
   - 动效克制：落子弹跳、胜利连线、思考呼吸点，其余一律 ≤160ms 微过渡；
   - 固定深色棋室色板，不跟随 TG 浅色主题（老板实测：浅底上深面板混搭、
     浅灰小字与深色正文都看不清；任何主题下统一呢绒黄铜，对比稳定）。
