name: Build & push images

# Build the SERVER (API + SPA) and VISION (ANPR) container images and push them to the
# house Gitea registry, tagged by BRANCH + short SHA (branch-aware: dev→:dev, stage→:stage,
# main→:main). Separate from ci.yml (checks-only) and release.yml (tag-only desktop bundle).
# Mirrors the house pattern (cf. trm/processor build.yml). See
# wiki/decisions/container-deployment.md and fleet-deployment-komodo.md (dev→stage→main tiers).
