/* ==========================================================================
   账户 / 同步组件样式（acct.css）· 自包含 · 固定色值
   --------------------------------------------------------------------------
   账户挂件、登录弹层、账户切换器、同步状态胶囊的完整样式。
   供未引入 style.css 的页面（如 teacher-workbench.html）单独引入，
   确保「切换账户」组件在全站样式一致。

   重要：本文件刻意使用固定色值（不依赖 :root 主题变量）。
   因为像 teacher-workbench.html 这类页面有自定义主题变量（且同名不同值，
   如 --accent/#danger 与全站相反），若依赖变量会导致账户组件在不同页面
   颜色不一致。固定色值保证账户组件在任何页面外观统一。
   注：色值与 css/style.css 中 .acct* / .sync-* 保持一致；
       已引入 style.css 的页面本就含这些样式，无需再引本文件。
