pages/
  cross_new.js         # Updated grid generator page
  uziomy_new.js        # Updated grounding calculator page
```

### Color System
- **Primary**: Blue (#3B82F6) for main actions
- **Secondary**: Gray tones for secondary elements
- **Success**: Green for positive states
- **Warning**: Yellow for attention states
- **Error**: Red for error states

### Typography Scale
- **Headings**: Inter font with proper weight hierarchy
