 ## CI: build and push
 
 `.gitea/workflows/docker.yml` builds the image with Gitea Actions and pushes it
 to the Harbor registry as `registry.traberph.de/public/interval_viz`.

+The `main-…` tags sort by build time via the trailing timestamp. Flux image
+automation can pick the newest one with this filter:

+Old tags are cleaned up by a tag retention policy in Harbor, not by this workflow.
