/**  =================== 登录页样式 ===================  **
 *  2026-09-21 美化重写（原 WaitAdmin 默认「左图右表单」版式）
 *
 *  版式：卡片式两栏 —— 左品牌蓝渐变面板 / 右白色登录表单
 *        ≤880px 自动折叠为「顶部品牌条 + 表单」单栏
 *  主色：--lg-primary 与官网品牌蓝一致（登录页是门面，先立品牌）
 *       若日后想让登录页跟随后台主题色，把 --lg-primary 改成
 *       var(--theme-color, #1B4DFF) 即可（后台主题色由 theme.css 提供）
 *  注意：改完本文件要同步改视图里的 ?v= 版本号，否则用户端吃浏览器缓存
 *  ==================================================  **/
