 *  三、CSS变量
 *  建议使用CSS变量定义主题色，方便用户微调：
 *  --bg, --fg, --muted, --accent, --card, --shadow-light, --shadow-dark
 *  --radius, --radius-sm, --radius-lg
 *
 *  四、响应式
 *  主题必须支持移动端适配，使用 @media 断点：
 *  - 768px: 平板
 *  - 480px: 手机
 *
 *  五、开发流程
 *  1. 在 theme/ 下创建新文件夹（如 theme/mytheme/）
 *  2. 创建 style.css，定义上述所有CSS类
 *  3. 在后台"网站设置"中选择新主题
 *  4. 可选：添加自定义字体、图片等资源
