 * and network request/response data to the {@link browserLogger} and

 * {@link FlowLogBufferTransport} that captures entries into the per-flow
 * log buffer (when one is available via AsyncLocalStorage or the process-local

 * This function is called from both {@link WebTargetInspector.handleNewPage}
 * (Studio-launched flows) and the Playwright test extension fixture, ensuring
 * identical logging behaviour across both runtime contexts.
