Circular Gallery

You are given a task to integrate an existing React component in the codebase

~~~/README.md
# CircularGalleryShowcase

A high-end, WebGL-powered circular gallery with smooth inertia-based scrolling and distinctive bending effects. Built using the OGL library for high-performance rendering.

## Dependencies
- `ogl`: ^0.0.116
- `react`: ^18.2.0
- `react-dom`: ^18.2.0

## Props

| Prop | Type | Default | Description |
|------|------|---------|-------------|
| `items` | `{ image: string; text: string }[]` | (sample images) | Array of images and labels to display |
| `bend` | `number` | `3` | Intensity of the circular bending effect |
| `textColor` | `string` | `"#ffffff"` | Color of the item labels |
| `borderRadius` | `number` | `0.05` | Normalized border radius for images (0 to 0.5) |
| `font` | `string` | `"bold 30px sans-serif"` | CSS font string for the labels |
| `scrollSpeed` | `number` | `2` | Sensitivity of wheel and touch scrolling |
| `scrollEase` | `number` | `0.05` | Inertia factor for smooth movement |
| `className` | `string` | `""` | Additional CSS classes for the container |

## Usage Example

```tsx
import { CircularGallery } from '@/sd-components/673e9361-200f-49eb-84ef-6ba609a4d2ce';

function MyGallery() {
  return (
    <div style={{ height: '600px' }}>
      <CircularGallery 
        bend={3}
        textColor="#ffffff"
        borderRadius={0.05}
        scrollEase={0.02}
      />
    </div>
  );
}
```

Implementation Guidelines

1. Analyze the component structure, styling, animation implementations
2. Review the component's arguments and state
3. Think through what is the best place to adopt this component/style into the design we are doing
4. Then adopt the component/design to our current system
