Day 19 and 20 - Deployment: From Local System to Live Product

Phase 6 covers deploying a full-stack project (React frontend on Vercel, Flask backend on Render) from local development to live production. Day 19 focused on synchronizing frontend-backend API contracts and selecting deployment platforms, while Day 20 addressed replacing mock data with live API calls, configuring environment variables, and establishing project maintainability through contribution guidelines, templates, and documentation.
