1. Does NOT recommend Inter, Roboto, Arial, Helvetica, Open Sans, Lato, Montserrat, or Poppins as primary fonts
2. Aesthetic direction is coherent with color approach (e.g., brutalist aesthetic doesn't pair with expressive color without explanation)
3. Font recommendations include specific font names (not generic like "a sans-serif font")
4. Color palette includes actual hex values, not placeholders like "[hex]"
5. Rationale is provided for major decisions (not just "because it looks good")
6. No AI slop patterns: purple gradients mentioned positively, "3-column feature grid" language, generic marketing speak
7. Product context is reflected in design choices (civic tech → should have appropriate, professional aesthetic)
