/* ============================================================
   7鬼523 横屏原型 · 基础样式（V2 返修版）
   目标：明亮蓝绿桌面 + 高清牌面 + 金色主操作按钮；
        · 640×360 与 844×390 一屏完成创建/准备/牌桌/设置/退出；
        · 一字不换行：按钮、昵称、标签都不许逐字竖排；
        · 竖屏不硬塞牌桌，只保留"横屏玩 / 离开 + 核心状态"的简洁页。
   横竖屏与尺寸分档只认 html[data-*] 标记（见 layout.js）。
   高度预算（360）：顶栏 44 + 状态条 22 + 牌桌 122 + 操作区 56 + 手牌 116
   高度预算（390）：顶栏 46 + 状态条 22 + 牌桌 140 + 操作区 58 + 手牌 124
