Independently compare the original reference images with real Playwright screenshot artifacts at every required viewport. Verify artifact identities, then assess perceptual/pixel/edge differences, responsive layout, browser behavior, and accessibility separately. Link every mismatch to a reference and render artifact. If either side is absent or not a real image artifact, return blocked; never infer visual conformance from HTML, DOM text, or a preview manifest.
