# Build and publish the production container image to GHCR.
#
# The image at packages/api/Dockerfile is the single deployable artefact:
# Express + bundled SPA + /v1/traces ingest, all served on one port. This
# workflow is the upstream side of any deployment — downstream operators
# can pull from GHCR and re-tag into their own private registry if their
# policy requires it.
#
# Triggers:
#   - manual workflow_dispatch only (intentional — operator runs builds
#     when they want them, not on every push). Once the build path has
#     been exercised a few times and a release cadence is in place, a
#     `push: branches: [main]` and/or `push: tags: ['v*']` block can be
#     added back so :latest moves automatically.
