name: Build & Push Images

# Builds the frontend + backend Docker images and pushes them to the Forgejo
# container registry (registry.snsnetlabs.com/sam/...). Runs on every push to
# main, and on-demand via the "Run workflow" button (workflow_dispatch).
#
# NOTE: registry.snsnetlabs.com is the unproxied (DNS-only) registry host so
# large layers bypass Cloudflare's body cap. The web UI / packages list stays
# on forgejo.snsnetlabs.com (Cloudflare Access SSO).
#
# Requirements (see deploy/README.md):
#   - Forgejo Actions secret FORGEJO_REGISTRY_TOKEN: a package-scoped token for
#     user `sam`.
#   - The runner must allow Docker builds: container.docker_host = "automount"
#     in the forgejo-runner config (mounts /var/run/docker.sock into the job).
