This performs a structured WCAG 2.1/2.2 compliance audit against the four POUR principles (Perceivable, Operable, Understandable, Robust). You feed it interface descriptions, URLs or screenshots, and your target conformance level, and it evaluates against the success criteria that actually matter for legal compliance. Most organizations need Level AA, which this prioritizes. It's thorough on the critical stuff like contrast ratios, keyboard navigation, focus indicators, and semantic HTML. Use it when you're preparing for accessibility certifications, responding to complaints, or just trying to avoid ADA lawsuits. Pairs well with general usability audits since accessibility and usability overlap heavily but aren't identical.
