   都市头条 H5 / 平板适配样式 (responsive.css)
   =====================================================================
   断点体系（与 flexible.js 严格对应）：
     >= 1200px          PC —— 本文件所有规则均不生效，PC 端零影响
     768 ~ 1199.98px    平板 —— 布局降级（栅格减列、双栏堆叠），1rem = 16px
     < 768px            手机 —— 等比缩放布局，1rem = 屏宽 / 3.75
                         （以 375px 设计稿为基准：1rem = 100px，
                          即 0.32rem = 32px@375 屏、0.44rem = 44px@375 屏）

   书写约定：
     1. 全部规则包裹在 @media (max-width: 1199.98px) 内，保证 PC 不变；
     2. 手机端尺寸优先使用 rem（随屏宽等比缩放，小屏自动缩小）；
     3. 仅做"覆盖"，不修改 style.css / index.css 等既有 PC 规则；
     4. 引入位置：置于所有既有样式表之后（覆盖依赖加载顺序）：
        <link rel="stylesheet" href="/templates/default/css/responsive.css">
