/* ============================================================
   化识助手 网页改版 第 0+1 期（2026-11-06）
   - 第 0 期：design tokens（色/字阶/间距/圆角/阴影/字体栈）
   - 第 1 期：共享顶栏 + 通用组件（按钮/卡片/表格/表单/徽章）
   中英文站都加载（模板条件 web_ui_v2；英文站 2026-11-06 起接入，英文专属覆盖见文末 .loc-en 段）；
   回退：环境变量 WEB_UI_V2=0 后 restart，即不再加载本文件，回到旧观感。
   只做覆盖，不改 style.css。
   第 2 期（逐页重排：数据库/首页/个人/群组）见文末；页内内联样式先收为页内 class（旧取值不变），
   再在这里覆盖，保证 WEB_UI_V2=0 时与旧观感逐像素一致。第 3 期：admin 内联样式清理。
