Delete Branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

I’m trying to download a database backup that’s around 3GB in size. When initiating the download via the web UI, the request appears to hang for a very long time, and the browser doesn’t start receiving any data until the entire backup is fully prepared.
From the user’s perspective, it looks like the download is stuck or loading forever, rather than progressively downloading.
Expected Behavior
Ideally, large backups should be streamed to the client (through using HTTP chunked transfer or maybe ranged responses), so that the download can start immediately and the browser shows download progress instead of waiting for the full backup to be ready.
This would significantly improve UX for large backups and reduce the perception that the download is stalled or broken.
