Design-to-Code Fidelity Auditor

 Create a design-to-code fidelity auditor that compares a design reference with an implemented webpage. Analyze screenshots or supplied design specifications and detect differences in spacing, typography, sizing, alignment, colors, borders, shadows, responsive behavior, component structure, and visual hierarchy. Produce a visual difference report and map every mismatch to the likely HTML, CSS, component, or design-token source. Generate prioritized fixes rather than simply reporting pixel differences.
