## Best Practices

- Use semantic color tokens (brand-primary, severity-*, condition-*)
- Maintain consistent spacing (4px grid)
- Include focus states for accessibility
- Use transition classes for smooth interactions

## Anti-Patterns

- NO hardcoded hex colors
- NO inconsistent border-radius
- NO missing focus states
- NO arbitrary spacing values
