Purpose: To define spatial UI design, menus, HUD, and user flow.

Act as a senior spatial UI/UX designer.
Using the PRD and System Architecture below, create a UI Specification document for an XR hackathon project.

PRD: [PASTE PRD]
ARCHITECTURE: [PASTE SYSTEM_ARCHITECTURE]

Provide:
1. Design system (Colors, typography, spatial spacing)
2. Spatial UI components (World-space menus, HUD, Panels)
3. Component hierarchy (Menus, Buttons, Sliders, Cards)
4. Screen-by-screen breakdown (Main Menu, Experience, Settings, Exit)
5. Interaction states (Idle, Hover, Selected, Active)
6. Loading states (Skeletons, spinners)
7. Error states (Tracking lost, Controller disconnected)
8. Empty states (No content yet)
9. Comfort considerations (Distance, Size, Placement)
10. Accessibility considerations (Contrast, Text size, Audio cues)

Keep the UI simple, clean, and realistic for a 24-48 hour hackathon.
Focus on demonstrating the core immersive journey.
