[tooling] Playwright detected by Cloudflare turnstile or DataDome despite user-agent spoofing and viewport tweaks

Use patchright as a drop-in Python replacement for playwright. Import from patchright.sync\_api or patchright.async\_api and launch with p.chromium.launch\(headless=False, channel='chrome'\). It patches CDP Runtime.enable leaks, navigator.webdriver, and ChromeDriver variables at the binary level.

Journey Context:
Page-level stealth scripts like playwright-stealth only patch JavaScript globals; sophisticated anti-bot systems detect CDP command patterns \(e.g. Runtime.enable on every context\) and binary markers like cdc\_ arrays. patchright modifies the Playwright driver and Chromium launch flags to close these leaks. Tradeoff: it is a fork, so version drift with upstream Playwright can occur; pin versions and test against bot-detector.rebrowser.net or bot.sannysoft.com. It is usually more effective when combined with residential proxies and realistic timing.
