/* ==========================================================================
   law28 · 律砚网 全站样式
   版面语言：灰阶文书 · 朱批
     · 签名结构 1：页头 6px「墨黑 + 朱批」双色带
     · 签名结构 2：区块标题 = 朱批方印 + 等宽编号 + 通栏引线 + 左端朱批短线
     · 签名结构 3：巨型汉字水印（法 / 典 / 讯 / 砚，aria-hidden，不参与对比度扫描）
     · 签名结构 4：表格化台账行（行号列 + 悬停朱批左条），双列 / 三列两种无缩略图列表
   零 CDN：系统字体栈 + 内联 SVG sprite + 本地 SVG 图片；CSS 全站零 background-image
           （为的是让对比度探针取到真实底色，不被渐变遮住）
   防回归约定：
     · .wrap 用「宽度收缩 + 居中」，不用 padding —— 结构上不可能被 padding 简写清零
     · svg 与 img 绝不同写一条复位规则；.i 只在「没有 width 属性」时才由 CSS 兜尺寸
     · .sprite 必须零尺寸绝对定位，否则会在页首撑出 300×150 空白
     · 深色区里的浅色卡片必须显式声明 color（含卡内 h1~h4），否则白底白字
     · 中文栏宽用 em，不用 ch
     · 所有媒体查询集中在文件末尾，避免被后面的基础规则反压
