What environment variables are required?

You must set `R2_ACCOUNT_ID`, `R2_ACCESS_KEY_ID`, `R2_SECRET_ACCESS_KEY`, and `R2_BUCKET_NAME`.

How do I get R2 credentials?

In the Cloudflare Dashboard, create an R2 bucket, then generate an API token with read/write permissions and note the Access Key ID and Secret Access Key.
