    "Headless new, stock default args include --enable-automation; explicit --no-proxy-server and --no-sandbox match earlier browser host policy. No stealth plugins, UA override, preload script or interception.",
    "createBrowserContext isolates cookies/local storage; newPage viewport explicitly 1280x720 to match earlier Playwright. Initially empty cookies; normal session cookies allowed and discarded.",
    "One goto issues Page.navigate once; DOMContentLoaded 20s, settle 2s; no application retries. Browser-native resource retries/reconnections and page-script navigation are not disabled or independently counted as wire requests.",

    "Worker/browsers closed then supervisor cleans only recorded owned PID/start-time identities. PSS includes imports, full observed browser tree, DOM, PNG and exit, excludes Python/checks."
