* 环境变量加载策略（后加载的文件覆盖先前的同名键）：
|
||
*
|
||
* - local：`.env` + `.env.local`
|
||
* - staging：`.env.staging` + `.env.staging.local`（同机测试栈，APP_ENV=staging）
|
||
* - production：`.env.production` + `.env.production.local`
|
||
*
|
||
* 判定：优先 `APP_ENV`；未设置时 `NODE_ENV=production` → production，否则 local。
|
||
* staging 在 PM2 中仍设 `NODE_ENV=production`（构建产物），靠 `APP_ENV=staging` 区分。
