XR (Extended Reality) architecture for immersive blockchain exploration experiences.

## WebXR Integration Strategy

### Primary Approach

**Technology**: WebXR API
**Benefits**: Browser-based, no app installation
**Limitations**: Device compatibility

### Fallback

**Unity/Unreal**: Native apps for high-fidelity experiences
**Use Case**: Advanced XR features, better performance

## Shared Backend API Usage

**Strategy**: XR clients use same APIs as web/mobile
**Benefits**: Consistency, reuse, easier maintenance

## Scene Management
