  // 代理策略（后端 TenantHostMiddleware 事实源 app/platform/host_middleware.py：
  // 仅 /health 精确与 /api/platform/ 前缀豁免租户 Host 解析，其余按 Host 找租户）：
  // - /api/platform/*：豁免前缀，changeOrigin 直转即可（Host=127.0.0.1:8018 无碍）；
  // - /api/public/*：品牌/头像公开端点依赖租户 Host——用 headers.Host 改写成
  //   VITE_TENANT_PREVIEW_HOST（种子租户域名），changeOrigin 必须为 false
  //   否则 Host 会被改回目标地址使解析 404；
  // - /static/*：静态资源同样过租户解析，与 /api/public 同策略。
  // 注意对象键序：更长的 /api/public 前缀必须排在 /api 之前（http-proxy 按序首配命中）。
