//                 Requires Docker. globalSetup boots the containers once per
//                 run; each test file gets its own database cloned from a
//                 template (see __tests__/integration/support/).
// Running only unit tests (vitest run --project unit, or a file filter that
// matches nothing under __tests__/integration/) starts no containers.
