# `gitea.event_name == 'push'`, so a PR run compiled all three platforms and
# produced nothing — and it ran alongside build-app-preview.yml, which compiles
# the same three and publishes them. Six OS builds per push, one set of which
# was unreachable. Previews now carry the PR check; this workflow is releases.
