+ * Unlike the main playwright.config.ts, this config:
+ * - Does not start a local dev server (specs navigate to absolute URLs).
+ * - Runs tests sequentially to avoid rate-limiting external APIs.
+ * - Enforces forbidOnly unconditionally (probers always run in CI).
+ * - Captures screenshots, video, and traces for debugging live failures.
