Technology Stack

• Frontend: HTML5, CSS3, JavaScript ES6+
• 3D Rendering: Three.js
• Build: No build system (vanilla JS)
• Testing: Jest or Mocha for unit tests

Development Phases

1. Phase 1: Basic project structure and HTML layout
2. Phase 2: Three.js renderer setup with camera and scene
3. Phase 3: Track piece system with placement
4. Phase 4: Grid and world management
5. Phase 5: Junctions and signals logic
6. Phase 6: Driver's eye view feature
7. Phase 7: Game state save/load
8. Phase 8: Testing and documentation

Next Steps

• Create project file structure
• Set up Three.js renderer
• Implement basic track pieces
• Build placement interface
