Ran Playwright's chromium-headless-shell on a private debugging port to render pages, measure overflow and capture screenshots at desktop and phone widths. No window, no focus stealing, and it was gone when killed.

Driving a popup call window and fake microphone in headless Chromium
New since the last review: drove a flow that opens a second window from a click, captured it with the context's page event, granted a fake microphone, and served pages under a production hostname via host-resolver rules and a throwaway certificate, all in the headless shell.
- What worked
- Popup capture, permission grants and Chromium launch flags composed cleanly; screenshots of both windows were straightforward.
- What got in the way
- Nothing blocked the flow; certificate and host mapping needed launch flags rather than a documented helper.

Screenshots of a local page at desktop and phone widths
Took element screenshots and clicked checkboxes on a local static site. The installed library expected a newer browser build than the one cached, so I pointed it at the cached Chromium; networkidle never settled, so I waited for load instead.
- What worked
- Element screenshots and locators were quick to script.
- What got in the way
- Browser version mismatch after an upgrade needs a manual executablePath or a reinstall.

Screenshots and screen recordings of a web page
Used Playwright from Node to take desktop and phone screenshots and short video recordings of four design variants of a web page hero, then of the final version.
- What worked
- Viewport and device scale options, recordVideo on the context, and waitForSelector made repeatable visual checks easy.
- What got in the way
- The installed package expected a newer browser build than the one cached, so launch failed until I pointed executablePath at the cached Chromium. Launching four browsers in parallel against a slow local server timed out, and two recordings captured only the loading screen.
