# J621 CD — manual release workflow (Actions tab -> "Run workflow").
#
# One dispatch does everything:
#   * builds and pushes the backend + frontend images (multi-arch, :latest
#     and :<short-sha>, GIT_HASH baked in for the version pill),
#   * builds the desktop packages and attaches them (plus the update
#     metadata) to the Gitea release tagged `desktop-v<package.json version>`.
#
# The live update feed (deploy/data/desktop, served by the frontend nginx at
# /desktop/) is not touched here: it is runtime state on the deploy host and
# is still published with `deploy/push_desktop.sh --no-build` from a machine
# that can reach it.
#
# Registry login uses the REGISTRY_USER / REGISTRY_TOKEN repo secrets.
# Jobs run on the user-scoped nitro-ci runner (ubuntu-latest).
