/* ===== 第 71 轮：移动端字号基准 =====
   背景：本文件原来的 html,body{font-size:12.5px} 会把 media-public.css 的
   移动端根字号阶梯（1200→10px … 375→4px）覆盖掉，导致本页元素按 12.5px
   基准渲染，视觉上比首页/产品页大 3 倍以上（用户反馈「页面特别大」）。
   处理：① 删除 12.5px 覆盖，让根字号回归统一阶梯；② rem 尺寸随根字号
   等比缩小后，em 链条会掉到 4px 级别（字小到不可读），因此给内容区块
   补一层 12px 的 px 基准 —— 与产品页、案例页的做法一致（容器给 px 基准，
   内部 em 相对它计算）。 */
