   一、响应式规范

   断点（对齐 Bootstrap 5 / MDB，全站唯一一套，勿再新增其它数值）
     xs  < 576px     手机
     sm  576–767px   大屏手机
     md  768–991px   平板竖屏
     lg  992–1199px  小笔记本 / 平板横屏
     xl  1200–1399px 常规桌面
     xxl ≥ 1400px    大屏（1920 起按设计稿 1:1）
   本文件按 max-width 递进覆写，实际使用 4 档：1400 / 1200 / 992 / 576
   （例外：.sc-container 的 max-width 阶梯沿用 .container 的 min-width 写法）

   版心：与全站 .container 用同一套断点阶梯，只有左右留白更宽
     容器 max-width：576 / 768 / 992 / 1200 / 1400 起依次 540 / 720 / 960 / 1140 / 1320
       （< 576px 不设上限，满宽）
     左右留白 --gutter = 24px（.container 是 12px）
     故 ≥1400 时内容净宽 = 1320 - 48 = 1272，比 .container 少 24px

   字号：桌面端一律用 px token（--fs-*），严格还原设计稿；
        需要在移动端缩小的字号，在对应断点内手写 rem，
        最终 px = rem × 根字号（根字号依次为 16 / 15 / 14 / 13）

     移动 / 平板：Hero 媒体框整体等比缩小
     原写法 --hero-media-scale: min(1, calc((100vw - 64px) / 720)) 是无效的：
       「<length> ÷ <number>」得到的是 <length>（如 0.43px），不是无单位比值；
       min(1, <length>) 混用 <number> 与 <length> → 表达式非法，
       var() 代入 width / height 后声明「invalid at computed-value time」→ 回退 unset，
       height 变成 auto；而 ::before / ::after / -inner / slogan 全是绝对定位，
       父级没有内容撑高，于是 .sc-hero-media 高度为 0，边框与视频一起塌陷。
     改法：父级 width:100% + max-width 跟随版心（不再用 100vw 硬算，避免 576–991
          段版心有 max-width 时溢出），aspect-ratio 锁定设计稿 720:488；
          子元素改用 720×488 的百分比定位（横向按容器宽、纵向按容器高换算，等比成立），
          只有 slogan 字号保留固定 token，彻底不依赖 var() 参与 calc。
