/* ==========================================================================
   后台样式（前后端不分离版）
   --------------------------------------------------------------------------
   设计原则：
   1. 视觉对齐现有 Vue 后台（supply_admin / registration_admin）：
      侧边栏 172px 白底、顶栏 50px、内容区 #f0f2f5、主色 #409eff
   2. 零构建、零外部依赖：不依赖 Tailwind / Bootstrap / CDN，
      直接用浏览器原生 CSS，断网也能正常显示
   3. 类名按「组件 + 修饰」命名（如 btn btn-primary），与 Element Plus 的
      视觉习惯对应，方便后续从 Vue 后台对照迁移
