# CI: every pull request and every push to main must pass these checks
# (ADR 0014). The deploy pipeline (CD) lives in cd.yml and only runs on
# main after this workflow's quality bar.

# Runner requirements: an act_runner with the `ubuntu-latest` label and
# Docker access (see deploy/stages.md, issue #9).
