11. ERROR_HANDLING.md

Purpose: To define what happens when tracking is lost, a controller disconnects, or performance drops.

You are a senior XR developer.
Using the System Architecture and Interaction Spec below, create an Error Handling document for an XR hackathon project.

ARCHITECTURE: [PASTE SYSTEM_ARCHITECTURE]
INTERACTION_SPEC: [PASTE INTERACTION_SPEC]

Provide:
1. Common failure modes (Tracking loss, Controller disconnect, Low battery, Performance drop)
2. Tracking error handling (Recenter, Pause, Fallback)
3. Controller error handling (Pause, Notify user, Switch to hand tracking)
4. Spatial mapping error handling (Re-scan, Anchor loss)
5. Performance error handling (Reduce quality, Pause rendering)
6. Frontend error display (In-world notifications, HUD alerts)
7. Recovery procedures (Auto-recenter, Manual reset)
8. A checklist for developers to verify error handling before the demo

Focus on making the experience resilient so the live demo does not crash.
Explain each error handling approach in beginner-friendly language.
