      # path, not /workspace) and sharing the host network so published test ports resolve as localhost.

      # blocks the merge.
      #
      # A PULL REQUEST MUST NOT TOUCH THE :latest TAG. This runner builds on the host's Docker daemon —
      # the same daemon the live container runs on — so retagging :latest IS a deployment: Watchtower
      # compares the running container's image against :latest, finds they differ, and recreates the
      # container from the locally built image. Gating only the push was not enough; on 2026-07-26 the PR
      # builds for this branch deployed unmerged code to itsthevine.com several times over, and each time
      # Watchtower's next pull of the (older) registry :latest reverted it. One of those deploys ran a
      # migration against the production database.
      #
      # So a PR builds pr-<number> instead, which nothing watches. Trivy scans whatever was built, and the
      # push step below still only runs off a PR.
