   法鉴网 · 法律资讯站 样式表
   零外部依赖：字体使用系统字体栈，图标使用文档内联 SVG 精灵，配图使用本地 SVG。
   约定：
   1) 只有 .wrap 负责左右留白，它只允许写 padding-left / padding-right；
      所有与 .wrap 叠用的修饰类（.header-main / .topbar__inner / .crumb__inner …）
      一律只写 padding-top / padding-bottom，避免简写把左右留白清零。
   2) 任何装饰性渐变/纹理都挂在区块的 ::before 上，区块自身只留纯色背景，
      这样对比度审计能正确取到底色，也避免半透明叠层干扰。
   3) 栅格子项统一 min-width:0，长文本统一 overflow-wrap:break-word。
