 * Xtream Codes E2E Tests

 * the Angular dev server when running e2e tests (see playwright.config.ts).
 *
 * Default scenario (user1:pass1) provides:
 *   - 8 categories per content type (live / VOD / series)
 *   - 40 items per category
 *   - 3 seasons × 8 episodes per series item
 *
 * Tag: @xtream — run only Xtream tests with: nx e2e web-e2e --grep "@xtream"
