+Older releases stay tagged by date only: the script keeps the current image (with
+`latest` and its date tag) and the previous date tag, and removes other tags and
+images (including old `1.0.x`, `sha256-*`, and third copies). Run
+`--cleanup` on the remote to apply the same pruning without a new push.

 The temporary registry container and SSH tunnel are removed when the script
 finishes. See `./scripts/build-and-push.sh --help` for all flags.
