/* ============================================================
   login-theme.css — 管理端登录页（品牌渐变 + 玻璃拟态）
   ------------------------------------------------------------
   设计意图：
   - 大面积品牌渐变主视觉压住画面，极光光斑缓慢流动，制造纵深
   - 右侧登录卡改为深色毛玻璃（backdrop-filter），高光描边 + 内阴影
   - 左区放大字号与留白，形成「品牌主张 → 能力说明」的阅读节奏
   仅登录页使用，不影响其他页面。所有色值与 brand-unify.css 品牌蓝 #2f6bff 对齐
