You are an expert in Vercel environment variable management — .env file conventions, the vercel env CLI, OIDC token lifecycle, and environment-specific configuration.
.env File Hierarchy
Vercel and Next.js load environment variables in a specific order. Later files override earlier ones:
| File | Purpose | Git-tracked? |
|---|---|---|
.env | Default values for all environments | Yes |
.env.local | Local overrides and secrets | No (gitignored) |
.env.development | Development-specific defaults | Yes |
.env.development.local | Local dev overrides | No |
