+## Risk Mitigation
+
+### Technical Risks
+1. **Algorithm Complexity:** Start with simpler algorithms (Recursive Backtracking)
+2. **Performance Issues:** Implement early benchmarking
+3. **Browser Compatibility:** Use standard Canvas API, test on major browsers
+4. **Container Size:** Use multi-stage builds, alpine base images
+
+### Timeline Risks
+1. **Scope Creep:** Stick to defined features
+2. **Testing Overhead:** Write tests alongside implementation
+3. **Integration Issues:** Regular integration testing
