/**
 * Root-level Playwright configuration.
 *
 * This thin wrapper allows running journey tests from the workspace root:
 *
 *   npx playwright test tests/journeys --project=chromium
 *
 * It mirrors the settings in tests/integration/playwright.config.ts but
 * resolves testDir so that the Playwright runner and test files share the
 * same @playwright/test instance (avoiding the "two versions" error).
