post-deploy-visual-check overview

Post-deploy visual check — after a production deploy, spin up Playwright against the live URL, walk a configurable set of critical flows, capture full-page screenshots, and emit a self-contained HTML report so a human reviewer can verify the deploy looks right before handing off. Motivation: traditional smoke tests (HTTP 200, login form renders) often pass while a production-only UX regression slips through. The canonical example: a banner that renders conditionally on a flag set by the server for new fallback-draft records; the banner CSS ships fine, the server flag ships fine, but the pair isn't exercised because the e2e suite uses seeded fixtures that never hit the fallback path. A quick visual walk of 4–6 critical flows catches this.
