/* =========================================================================
   Admin Auth · "Ink" design system（黑白双主题）
   ---------------------------------------------------------------------
   概念：黑白灰的冷淡安全控制台。墨色侧边栏 + 中性画布 + 墨色主按钮，
   彩色只留给"状态语义"（成功/失败/风险）与 client 配色 chip。
   - 主题：全部颜色用 light-dark() 成对声明；html[data-theme=light|dark]
     强制主题，缺省跟随系统（color-scheme）。切换入口在右上角。
   - 字体：Bricolage Grotesque（拉丁展示）+ Spline Sans Mono（数据）
           + 系统中文（PingFang）。
   - 动效：页面加载 stagger 上浮；hover 微反馈；尊重 reduced-motion。
