The web interface shows the service information, available API endpoints, application version (1.0.0), and real-time system information.

Testing Validation

All components have been tested and validated:

• ✅ Application builds successfully with go build
• ✅ All API endpoints return expected JSON responses
• ✅ Web interface renders correctly with proper styling
• ✅ Random origami selection works with time-based seeding
• ✅ System information collection functions properly

This documentation serves as a complete reference for understanding, maintaining, and extending the recommendation service within the Craftista application ecosystem.
