/* 日本立直麻将样式（与斗地主/21点/UNO 同一套视觉语言：暗绿毛毡牌桌 + 金色点缀 + 白色卡片面板）
 *
 * 本文件由 uno-game/public/style.css 派生：
 *   - 上方「共享部分」逐字复用，改动需与另外三个游戏保持一致
 *   - 已剔除 UNO 专属区块（.ucard* / .color-* / .draw-pile / .pile-* / .uno-btn / .catch-btn）
 *   - 下方「麻将专属部分」为本游戏新增，命名统一带 mj- / mahjong 语义
 * 牌面类 .mj-tile 及其 34 种花色类在 tiles.css 中定义，本文件负责布局与交互。
