// 构建输出：兼容既有 CI 的 mode 子目录（build:prod → dist/prod、build:ld → dist/ld、build:base → dist/base）；

// 各 mode 产物内容完全相同（VITE_* 恒 undefined），不存在按环境烧值问题。
// dev 读 .env.dev（import.meta.env.VITE_*）；build 时 .env/.env.production 不存在 → VITE_* 全 undefined，
// host.config.ts 自动跳过 → 线上仅走 env-config 接口。注意：勿新建 .env.production / .env。
