   组织方式（参考 ITCSS / SMACSS 的组件化思路）：
     1. 设计变量与基础重置
     2. 通用工具类
     3. 按钮
     4. 区块标题
     5. 首页 Banner
     6. 顶部导航栏（含 light 变体）
     7. Mega 菜单（桌面 + 移动端）
     8. 移动端抽屉菜单
     9. 语言切换
    10. 导航轮播 CTA
    11. 页脚（布局 / 亮色 / 暗色 / 响应式）
    12. 页脚二维码浮层
    13. 悬浮工具栏
    14. 深入了解产品（Service Entry）
    15. 行业场景（home3-service）
    16. 通用图标菜单（mega-menu-cards）
    17. 合作地图（Coop Map）
    18. 新闻分类筛选 Tabs
    19. 列表分页
   每个区块内部顺序：基础样式 → 状态(:hover/:active) → 伪元素 → 响应式 @media
