   --------------------------------------------------------------------------
   CSP: style-src 'self' —— 本文件承载全部自定义样式，
   模板中不允许出现 style="" 内联样式，也不允许外链 CDN / 字体。

   本文件只做三件事，不重复实现 layui 已有的组件样式：
     01 变量与基础微调
     02 后台布局补充（layui-layout-admin 的 header / side / body 细节）
     03 响应式断点（<=768 抽屉侧栏；<=480 细节）
     04 业务小组件（统计卡、提示块、分页容器、代码块、验证码、KV 表等）
     05 认证页（登录 / 两步验证 / 错误页）
     06 前台页（商品列表 / 查单 / 模拟收银台）

   命名约定：自定义类统一使用 ace- 前缀，避免与 layui 冲突。
