   明律网 · 全站样式（零 CDN 依赖：系统字体栈 + 内联 SVG 图标 + 本地 SVG 图片）
   设计语言：瑞士国际主义 —— 发丝级 1px 网格 / 全直角 / 黑白灰 + 交通黄
   --------------------------------------------------------------------------
   项目铁律（踩过的坑，改样式前先看）：
   1) 任何同时带 .wrap 的元素（.header-main / .topbar__inner / .footer-main /
      .crumb__inner / .page-banner__inner ...）禁止使用 padding 简写，只能用
      padding-block / padding-top / padding-bottom，否则 .wrap 的左右留白会被
      一并清零，内容贴屏、各区块左边距互相对不齐。本文件 .wrap 只负责
      width + margin，不含 padding，天然规避。
   2) .sprite{position:absolute;width:0;height:0;overflow:hidden} 必须存在，
      否则 <svg> 会以浏览器默认 300x150 在页首撑出一大块空白（横向审计查不出来）。
   3) img/video 与 svg 的复位规则必须分开写，不能合并成一条。
   4) 深色区里的浅色卡片，容器与卡内 h1~h4 必须显式声明 color，否则白底白字。
   5) 浅底用的三级灰（--muted）与深底用的三级灰（--on-dark-2）是两个令牌。
   6) 一页只能有一个 h1；内页 banner 的栏目标题用 <p>。
