#   push to dev      -> :dev
#   push/merge main  -> :latest
#   git tag v1.2.0   -> :v1.2.0 and :stable
#   git tag v1.2.0-rc.1 (pre-release) -> :v1.2.0-rc.1 only, :stable stays
# Tests run once per code state (.gitea/scripts/build-plan.sh): main skips them when :dev was built
# from the same code, a tag on the commit of :latest only retags it. The images carry commit and git
# tree as labels for this, so no extra tags end up in the registry.
