This is for when you need ruthless visual QA that assumes nothing worked until proven otherwise. It analyzes screenshots and UI changes with pixel-level precision, validating everything from responsive breakpoints to WCAG contrast ratios without looking at your code. The workflow is skeptical by design: describe what's actually visible, measure rotations and positioning changes, actively hunt for failures, and never declare success without concrete visual proof. It covers the full spectrum from automated tools like Percy and Chromatic to manual inspection techniques, accessibility overlays, and cross-browser matrix testing. If you're shipping UI changes and want validation that doesn't give you the benefit of the doubt, this brings the rigor.
