# Checks only — completely separate from deploy.yml (which SSHes to the droplet
# on push to main). This never deploys; it runs typecheck, lint, and unit tests
# on every PR and on main after merge, so a type/lint/test regression is caught
# before (and independently of) a deploy.

    # NOTE: the integration suite (pnpm test:integration) and Playwright e2e are
    # not wired here yet — they need a Supabase/Postgres service in CI. Adding
    # that (and failing the run if the integration suite executes 0 tests, so a
    # missing DB can't masquerade as passing) is the next CI step.
