   DSA 统一身份认证 —— 前端设计系统（Fuwari / Ethereal 风格）

   设计语言参考 halo-theme-ethereal（Fuwari 系）：
     · 以 oklch 表达的低饱和主色 + 同色相浅底，柔和而不刺眼
     · 大圆角（1rem）+ 极轻投影 + 悬浮时轻微上浮
     · 玻璃拟态导航（saturate + blur），滚动后收拢为浮动胶囊
     · 入场 fade-in-up 交错、滚动渐显、换页淡出
     · 深浅色同构：只换令牌，不改结构

   结构约定
   --------
   本文件在 Bootstrap 之上工作：Bootstrap 负责栅格与组件行为，
   这里接管**视觉**（配色、圆角、阴影、动效）。因此
     1) 先覆盖 Bootstrap 的 CSS 变量（--bs-*），让它的组件自动跟随；
     2) 再逐组件精修（.btn / .card / .form-control / .table …）；
     3) 最后是自定义组件类（.dsa-*）。
   修改配色只需改第 1 节的令牌，不要在组件里写死颜色。
