   law29 · 律衡网 全站样式
   版面语言：青瓷天平 · 卷标
     · 签名结构 1：深青 hero（刻度盘线稿 + 巨型「衡」水印）+ 右侧「今日要闻」板
     · 签名结构 2：区块标题 = 圆形竖排编号 + 中文标题 + 通栏细线 + 左端琥珀短条
     · 签名结构 3：双列「时间轴」无缩略图列表（竖轨 + 圆点），三列「编号条目」列表
     · 签名结构 4：顶部深青信息条 + 白顶栏（吸顶）+ 页脚大字导航行
   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」，与 .wrap 同元素的容器只写 padding-block
     · 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，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
     · 侧栏栏体不吸顶、不内滚（类名里也不出现 sticky 字样）
