## Anti-Patterns (Do NOT Use)

- ❌ Generic tech design
- ❌ No viz

### Additional Forbidden Patterns

- ❌ **Emojis as icons** — Use SVG icons (Heroicons, Lucide, Simple Icons)
- ❌ **Missing cursor:pointer** — All clickable elements must have cursor:pointer
- ❌ **Layout-shifting hovers** — Avoid scale transforms that shift layout
- ❌ **Low contrast text** — Maintain 4.5:1 minimum contrast ratio
- ❌ **Instant state changes** — Always use transitions (150-300ms)
- ❌ **Invisible focus states** — Focus states must be visible for a11y
