STORAGE_ENDPOINT: set it for anything that is not AWS S3, leave it unset for AWS. Only these exact names are read, there is no fallback to S3_-prefixed ones.
Variables
Endpoints by provider
Backblaze B2 and other S3-compatible services work the same way: set their endpoint and a region.

Defaults leave every timeout off, which is fine on a fast link and unhelpful when the provider stalls. A reasonable production set:STORAGE_REQUEST_TIMEOUT well past 30000 if you accept large video uploads.
