// Playwright globalSetup — runs once before all e2e tests.
//
// Responsibilities:
//   1. Verify api/.env exists (Laravel needs APP_KEY etc.)
//   2. Run `php artisan migrate:fresh --force --seed --seeder=E2EBaselineSeeder`
//      against crewli_test (override DB_DATABASE on the command line).
//      The seeder writes seeded IDs to api/storage/app/e2e-fixtures.json.
//   3. Verify the fixtures file was produced.
//
// Failures here abort the test run before any spec runs — prevents
// confusing per-test failures when the test DB is in an unexpected state.
//
// Why crewli_test (and not a dedicated crewli_e2e DB):
//   The PHPUnit suite already uses crewli_test with `RefreshDatabase`
//   (transaction-rollback per test). Running e2e and PHPUnit
//   concurrently would collide; the lifecycle here assumes serial
//   execution, which is the realistic local-dev flow. Documented in
//   dev-docs/ARCH-TESTING.md §5 (mock-vs-real-backend).
