/* ==========================================================================
   VPN-OPS 前端样式（按 docs/DESIGN-frontend.md 落地）
   --------------------------------------------------------------------------
   结构：
     1. 设计令牌（CSS 变量，暗/浅两套）
     2. Element Plus 变量覆盖
     3. 基础重置与全局氛围
     4. 应用骨架（侧栏 / 顶栏 / 主区）
     5. 页面外壳（标题 / 工具栏 / 表单说明 / 空态）
     6. 数据展示（统计卡 / 表格 / 卡片 / 标签）
     7. 仪表盘（非对称布局 / 脉冲条 / 告警 feed / 趋势条）
     8. 业务局部样式（组织树 / 网段行 / 批量确认 / 登录页）
     9. 动效与状态（入场 / 悬停 / 按下 / 聚焦 / 骨架）
    10. 响应式（1200 / 900 / 640）
    11. 无障碍与降级（reduced-motion / 打印）
   硬约束：Vue3 CDN 无构建 SPA + Element Plus 2；改这里就能换肤，禁止在视图里写死颜色。
