asxpio's admin is getting a page for uploading files meant for public
use. They belong in the public bucket, which so far only the
public-upload key could write to. Grant asxpio's existing key put and
delete there instead of handing the app a second set of credentials.
Write-only is enough: the app keeps its own index of what it uploaded
and never reads the objects back.

Garage serves all three buckets and both apps, and a last comparison
found nothing in MinIO that Garage lacks. Drop the MinIO service, its
bootstrap and its root credentials from the deploy, and let compose
remove the leftover containers.
The storage_minio_data volume is left on the host. All images can be
pulled again, so the deploy goes back to failing on a pull error.
Document Garage in the README and SECRETS, including the key format and
how the existing secrets map to it, and swap the MinIO client in the
flake for awscli and rclone.
