/* ============================================================
   顶尖发卡平台 - 原生控件美化层
   作用：在 base.css 已有表单样式基础上，补齐浏览器原生控件的美化
   覆盖：select 下拉箭头、checkbox/radio、number spinners、
        date/file 控件、滚动条、错误态/禁用态、密码眼睛按钮
   原则：复用 :root 设计变量，不改动任何页面 HTML，最小侵入
   ============================================================ */
