   首页响应式样式（只作用于 body.page-home）
   ------------------------------------------------------------
   index.html 只有一套标记（PC 结构），靠本文件按宽度切换外观：
     >=1440px  → 完全沿用原 PC 样式，本文件不参与
     992~1439  → PC 样式去掉固定宽度，流式收缩
     <=991px   → 切成手机版外观：固定头 + 抽屉导航 / 横幅 + 焦点圆点 /
                 单列卡片 / 解决方案左右箭头翻页
   手机端用到的卡片外观尽量复用 /css/css.css（与内页手机版同源）。
