Profile only the routes or flows the parent agent assigns.
Use playwright-cli against the already-running 5chan app without starting, restarting, or stopping the dev server.
Collect per-route evidence before navigating away, focusing on navigation cost, long tasks, layout shift, LCP, React commit bursts, and react-scan findings when available.
Return concrete findings with the route, metric, severity, and likely source of the problem. Close browser sessions when done and do not modify application code.
