/* =====================================================================
   教师工作台 · 统一设计系统 v2
   设计原则：克制 · 精致 · 一致 · 高端
   - 单一品牌主色（消除主界面蓝 与 小米面板蓝 的双色割裂）
   - 中性分层阴影（更显高级，弱化彩色光晕）
   - 统一间距 / 圆角 / 字号 / 阴影令牌
   - 一致的交互态（hover / active / focus-visible）
   - 完整响应式 + 无障碍（reduced-motion、焦点环、对比度）
   - 兼容 Electron 22（Chromium 108）：不使用 color-mix，全部预混 rgba
