          </Card.Actions>
        </Card.Body>
      </Card>
    </ThemeProvider>

### Form Example

import { FormControl, Input, Button } from '@orchard9ai/design-system';

function LoginForm() {
  return (
    <form>
      <FormControl>
        <FormControl.Label>Email</FormControl.Label>
        <Input type="email" placeholder="Enter your email" />

        Sign In
      </Button>
    </form>
  );
}
```

### Using Utility Functions

```tsx
import { cn } from '@orchard9ai/design-system';

// Conditional class merging
const buttonClass = cn(
  'btn',
  variant && `btn-${variant}`,
  isLoading && 'loading',
  isDisabled && 'btn-disabled'
);

// Complex conditional styling
const cardClass = cn(
  'card',
  'bg-base-100',
  'shadow-xl',
  isActive && 'ring-2 ring-primary',
  isCompact && 'card-compact'
);
```

### Theme Switching

Using the ThemeProvider and useTheme hook:

```tsx
import { useTheme } from '@orchard9ai/design-system';

function ThemeSwitcher() {
  const { theme, setTheme, themes } = useTheme();

  return (
    <select
      className="select select-bordered"
      value={theme}
      onChange={(e) => setTheme(e.target.value as any)}
    >
      {themes.map((t) => (
        <option key={t} value={t}>
          {t}
        </option>
      ))}
    </select>
  );
}
```

## Theme System

### DaisyUI Semantic Colors

The design system uses DaisyUI's semantic color system:

- `primary` - Brand color (customizable per theme)
- `secondary` - Secondary brand color
- `accent` - Accent color for highlights
- `neutral` - Neutral grays
- `base-100/200/300` - Background layers
- `info/success/warning/error` - Status colors

### Available Themes

- **Light** - Clean, minimal light theme
- **Dark** - High-contrast dark theme
- **Cupcake** - Soft, pastel color palette
- **Business** - Professional, corporate styling
- **Grove Light** - Orchard9 brand theme with emerald accents on light background
- **Grove Dark** - Orchard9 brand theme with vibrant emerald on dark background

### Theme Implementation

```tsx
// Set theme on document root
document.documentElement.setAttribute('data-theme', 'light');

// Or use React state
function App() {
  const [theme, setTheme] = useState('light');

  useEffect(() => {
    document.documentElement.setAttribute('data-theme', theme);
  }, [theme]);

  return <div className="min-h-screen bg-base-100">{/* Your app content */}</div>;
}
```

## Testing Your Integration

### Verification Steps

1. **Install and import**: Ensure the package installs and CSS imports correctly
2. **Theme switching**: Test all 4 themes work properly
3. **DaisyUI classes**: Verify DaisyUI utilities are available
4. **Bundle size**: Check impact on your app's bundle size
5. **Build process**: Ensure production builds work correctly

### Example Test Component

```tsx
import { cn } from '@orchard9ai/design-system';
import '@orchard9ai/design-system/styles.css';

export function DesignSystemTest() {
  const [theme, setTheme] = useState('light');

  useEffect(() => {
    document.documentElement.setAttribute('data-theme', theme);
  }, [theme]);

  return (
    <div className="p-8 space-y-4">
      <h2 className="text-2xl font-bold">Design System Test</h2>

      {/* Theme Switcher */}
      <select
        className="select select-bordered"
        value={theme}
        onChange={(e) => setTheme(e.target.value)}
      >
        <option value="light">Light</option>
        <option value="dark">Dark</option>
        <option value="cupcake">Cupcake</option>
        <option value="business">Business</option>
      </select>

      {/* Component Tests */}
      <div className="space-x-2">
        <button className={cn('btn', 'btn-primary')}>Primary</button>
        <button className="btn btn-secondary">Secondary</button>
        <button className="btn btn-accent">Accent</button>
      </div>

      <div className="alert alert-success">
        <span>✅ Design system is working correctly!</span>
      </div>

      <div className="card bg-base-100 shadow">
        <div className="card-body">
          <h3 className="card-title">Test Card</h3>
          <p>Testing DaisyUI components in {theme} theme</p>
        </div>
      </div>
    </div>
  );
}
```
