    intensity?: number;                   // Light intensity 0-1 (default: 0.3)
  };
}
```

## 🔧 Custom Configuration

Create your own ellipse configurations:

```tsx
const customConfig = {
  backgroundColor: '#1a1a2e',
  shapes: [
    {
      id: 'custom-1',
      width: 80,        // Percentage of container width
      height: 30,       // Percentage of container height  
      x: -10,           // X position (percentage, can be negative)
      y: 20,            // Y position (percentage, can be negative)
      gradient: 'radial-gradient(ellipse, #ff6b6b 0%, #ee5a24 100%)',
      blur: 60,         // Blur intensity in pixels
      opacity: 0.7,     // Opacity (0-1)
      zIndex: 1,        // Stacking order
      shape: 'ellipse', // Shape type
    },
    // ... more ellipses
  ],
};

<MeshGradient customConfig={customConfig}>
  <YourContent />
</MeshGradient>
```

## 🖱️ Mouse Tracking

```tsx
<MeshGradient 
  theme="sunset"
  mouseTracking={{
    enabled: true,
    mode: 'attract',    // 'attract' or 'repel'
    intensity: 0.3,     // 0-1 strength
    radius: 30          // Effect radius in pixels
  }}
>
  <YourContent />
</MeshGradient>
```

## 🔮 Orb Mode

Create floating circular gradients perfect for AI assistants and modern interfaces:

```tsx
<MeshGradient
  theme="cyberpunk"
  shape="orb"
  size={85}
  animated={true}
  animationType="morph"
  containerAnimation="rotation"
  dropShadow={32}
  dropShadowOpacity={0.6}
  dropShadowDirection={{ x: 0, y: 12 }}
  lighting3d={{
    enabled: true,
    position: { x: 75, y: 25 },
    intensity: 0.8
  }}
/>
```

## 💡 3D Lighting & Shadows

Add realistic depth with lighting and shadows:

```tsx
<MeshGradient
  theme="deepSpace"
  lighting3d={{
    enabled: true,
    position: { x: 30, y: 30 },  // Light position (0-100%)
    intensity: 0.5               // Light intensity (0-1)
  }}
  dropShadow={25}                // Shadow size in pixels
  dropShadowOpacity={0.4}        // Shadow opacity (0-1)
  dropShadowDirection={{ x: 5, y: 10 }} // Shadow offset
>
  <YourContent />
</MeshGradient>
