/* ============================================================================
   全信 / OmniChat — Aurora Prism design system (v2, 2026 redesign).

   一套令牌同时服务用户前台（.shell）与运营后台（.console-root）：
     · 画布：曜石深空 + 极光弥散 + 细网格地平线 + 颗粒质感
     · 材质：双层玻璃（半透明底 + 顶部高光 + 渐变描边 + 环境投影）
     · 动效：弹簧曲线入场、列表逐条浮现、悬浮微位移、脉冲光晕
   全部图形与配色均为本项目原创。
