   同城资讯插件（yizhantang_new）公共样式 yzn.css
   视觉体系与 xigua_hb 西瓜分类信息手机版统一（custom.css 规范）：
   - 主色绿 #42bd56（对应西瓜 $config['maincolor']，经 --yzn-main 注入）
   - 白卡圆角 10px + 阴影 0 1px 10px rgba(0,0,0,.05)
   - hairline 分割 #e5e5e5 + scale(.5)；字号梯度 11/12/14/15/16px
   - 强调红 #ff6565 / 置顶黄 #ffda77 / 用户名蓝灰 #55657d / 链接蓝 #4f7cb8
   铁律：全部类名 .yzn- 前缀，双向隔离宿主（开发文档 4.5-3）
