/**
 * Playwright configuration for gitea-mirror E2E tests.
 *
 * Expected services (started by run-e2e.sh before Playwright launches):
 *   - Fake GitHub API server on http://localhost:4580
 *   - Git HTTP server on http://localhost:4590
 *   - Gitea instance on http://localhost:3333
 *   - gitea-mirror app on http://localhost:4321
 *
 * Test files are numbered to enforce execution order (they share state
 * via a single Gitea + app instance):
 *   01-health.spec.ts          – service smoke tests
 *   02-mirror-workflow.spec.ts – full first-mirror journey
 *   03-backup.spec.ts          – backup config toggling
 *   04-force-push.spec.ts      – force-push simulation & backup verification
 *   05-sync-verification.spec.ts – dynamic repos, content integrity, reset
