  # the multi-arch push build). The two jobs run in parallel; merge-manifest
  # then combines the per-platform images into the shared multi-arch tags.
  # A cache mount in the Dockerfile (persisted through cache-to: gha, mode=max)
  # keeps per-commit rebuilds to a relink instead of a cold Go compile.
