/*
 * 小宝游戏站 - 公共样式文件
 * 包含通用游戏组件样式
 *
 * 使用指南:
 * - 必须保留以下UI结构: #navbar, .home-btn, .navbar-title, .overlay
 * - 必须引用公共样式: ../assets/css/game-ui.css
 * - 必须使用主页链接格式: <a href="../" class="home-btn">🏠</a>
 * - 游戏独有逻辑只写在游戏目录内，不要影响其他游戏
 * - 分数实时显示在游戏画布右上角，不在导航栏中
 * - HUD规则：游戏开始前、进行中、暂停时、结束后都保持显示，不要隐藏
 * - 游戏结束后只保留"重新开始"按钮与逻辑
 * - 游戏事件跟踪函数位于 ../utils.js，包括 trackGameStart, trackGameEnd, trackEvent
 *
 * 🎨 游戏开发风格规范:
 * 1. 画布样式: 所有canvas元素统一使用霓虹青色边框
 *    #gameCanvas { border: 2px solid var(--primary-color); }
 * 2. 弹窗样式: 使用.overlay类,避免自定义背景色和透明度
 * 3. emoji使用: 适度使用,避免在弹窗和UI组件中过度使用emoji图标
 * 4. 颜色方案:
 *    - 主色调: --primary-color (#00f2ff) 霓虹青色
 *    - 辅助色: --secondary-color (#ff007f) 霓虹粉色
 *    - 强调色: #ffd93d 黄色 (用于分数)
 *    - 文本: --text-primary (白色), --text-secondary (灰色)
 * 5. 组件规范:
 *    - 画布边框: 统一霓虹青色,避免使用橙色/红色等其他颜色
 *    - HUD显示: 使用.hud-container系统,支持1-6个指标,单指标最小使用
 *    - 状态标签: 灰色标签文本,彩色数值保持可识别性
 * 6. 文案风格: 弹窗标题使用简洁文字,避免过度装饰
 *
 * 🎯 统一HUD系统规范:
 * - 结构: 一个玻璃态容器(.hud-container)包裹所有指标
 * - 布局: CSS Grid 3列布局,上下自动对齐
 * - 规则: 标签12px(灰色), 数值28px(可配置颜色), 垂直布局
 * - 最小使用: 游戏如只需分数,可只显示1个指标,无需强制使用多指标
 * - 最多指标: 第一行最多3个主指标,次级指标自动缩小25%
 * - 颜色类: hud-primary(青), hud-secondary(粉), hud-accent(绿), hud-warning(橙), hud-gold(黄), hud-white(白)
