docker-compose.yml mirrors the CI setup: MySQL 8 + FrankenPHP on a
shared named network. wp-cli runs in a container on that network so
DB_HOST=mysql works consistently. Makefile exposes three targets:
  make test-env   — first-time setup (downloads WP, starts stack)
  make test       — run the suite
  make test-reset — tear down and start completely fresh
