What makes it different

The underlying frontend-design skill teaches AI tools what not to do:

• Don't use Inter, Roboto, Arial (overused)
• Don't use gray text on colored backgrounds
• Don't use pure black or white (always tint)
• Don't nest cards inside cards
• Don't use bounce/elastic animations

These anti-patterns fight the "AI slop" aesthetic that makes generated interfaces look generic.
