   law27 · 法度网 全站样式
   设计语言：法治靛蓝 + 铜金 + 朱砂 + 象牙纸；标题用系统宋体做编辑感
   零依赖：无 @import、无外链字体、无 background-image 位图、图标全部内联 SVG
   防回归约定：
     · 与 .wrap 同元素的容器只写 padding-top / padding-bottom（简写会清掉左右内边距）
     · svg 与 img 绝不同写一条复位规则；.i 必须成对声明 width/height
     · .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（否则继承成白底白字）
     · 中文栏宽用 em，不用 ch
