beck-source/inventory-management — reverse-engineered prompt

Build me a clean factory inventory management demo app that a plant manager could use to see what’s going on across warehouses.

I want a dashboard with key numbers, filters, and charts for inventory, orders, demand forecasts, backlog, and spending. Users should be able to filter by warehouse, category, status, and month, then see the tables and metrics update. Include realistic mock factory data like circuit boards, sensors, actuators, controllers, orders across the year, demand trends, backlog items, and spending transactions.

Use a simple full stack setup with a Vue frontend and a Python FastAPI backend. Keep the data in memory or JSON files, no real database needed. Make it easy to run locally with separate frontend and backend commands, and include API routes for inventory, orders, demand, backlog, dashboard summary, and spending. The app should look polished enough for a workshop demo, with a modern dashboard feel and clear analytics.
