- **Summary:** Headless browser automation with Playwright and Chromium for UI testing, screenshots and page extraction; recommended default based on existing whynot-design, coulomb-social, core-hub and frontend-patterns implementations.
**Known limitations:**
- This is a dated source inspection; run the target-repo trial before claiming adoption success.
- Firefox is evidenced in frontend-patterns; WebKit is supported upstream but unverified in this inspection.
- Selenium is an optional testdrive-jsui dependency, not verified execution; Puppeteer has no verified example here.
