/* =============================================================================
   StarNexus Press · 登录界面品牌样式（本地新增 · 2026-09-27）
   -----------------------------------------------------------------------------
   本文件集中承载 .press 两个登录界面的视觉：
     1) .snx-admin-login   —— 后台登录（深色系）
     2) .snx-user-login    —— 个人中心 / 用户登录（浅色系 · 左品牌区 + 右表单区）

   设计约束（与设计报告一致）：
     · 只做视觉，不改任何登录逻辑、表单字段、跳转地址与权限校验
     · 品牌主色 #4A3A6B / 辅色 #D4AF37，与 .site 及 OIDC 中转页保持一致
     · 无障碍：正文对比度 ≥ 4.5:1，控件 focus 可见，尊重 prefers-reduced-motion
     · 纯 CSS，无外部依赖（不引第三方库、不引外网字体）
   ============================================================================= */
