-- [`event: Worker.console`] event is emitted when JavaScript within the worker calls one of console API methods, e.g. console.log or console.dir. [`method: Worker.waitForEvent`] can be used to wait for it. You can opt out of this using the `PLAYWRIGHT_DISABLE_SERVICE_WORKER_CONSOLE` environment variable.

-- Option [`property: TestConfig.webServer`] added a `wait` field to check readiness based on stdout/stderr.
+- Console messages from Service Workers are dispatched through [`event: Worker.console`]. You can opt out of this using the `PLAYWRIGHT_DISABLE_SERVICE_WORKER_CONSOLE` environment variable.
