Purpose: To design a realistic XR architecture with clear data flow from device to user experience.

Act as a senior XR architect.
Using the following PRD and TRD, design a realistic hackathon XR architecture.

PRD: [PASTE PRD]
TRD: [PASTE TRD]

Provide:
1. Recommended XR stack (Engine, SDK, Target device)
2. Complete XR architecture diagram (Text-based, showing User → Device → SDK → Scene → Interaction → Backend)
3. Scene architecture (Scenes, Prefabs, Controllers)
4. Interaction architecture (Input system, Hand tracking, Controllers)
5. Spatial mapping architecture (Anchors, Plane detection)
6. Rendering architecture (Pipeline, Shaders, Lighting)
7. Asset pipeline architecture (Import, Optimization, Loading)
8. Audio architecture (Spatial audio, Voice)
9. Backend/Cloud architecture (If applicable)
10. Data flow (How a user action becomes a scene change)
11. Performance considerations
12. Simplifications that can be made for a hackathon

Explain every technical decision in beginner-friendly language.
Do not introduce unnecessary tools. Prefer a simple architecture that can be explained easily to judges.
