TheSun-1712/Supply-Chain-Optimization ? reverse-engineered prompt

Build me a supply chain management dashboard that feels like a real SaaS app.

I want a backend and frontend where I can manage products, suppliers, inventory, orders, and shipments, then get AI suggested actions for what to do next. The app should also let me run simulations, compare different policies, test scenarios, and see useful analytics like performance over time, action mix, profit trends, and a scorecard.

Please make the UI clean and easy to use, with separate pages for inventory, recommendations, simulation, scenario testing, and analytics. The AI part should use the trained model already in the repo if possible, and the app should work locally with SQLite but be ready for PostgreSQL too.

If you need to look up current docs online, go ahead. Also include a simple setup so I can run the backend and frontend locally without much hassle, and make sure the API is wired up end to end.
