arpit168/Inventory-Management — reverse-engineered prompt

Build me a modern inventory management app for shopkeepers that feels polished and easy to use. I want secure sign up and login, protected pages, profile settings, and a forgot password plus reset password flow. The main dashboard should let me add, edit, delete, and update products and quantities, automatically flag low stock, show out of stock items, and keep a history of removed products.

I also want clear profit and loss summaries, dashboard cards and charts, a notification center with toast alerts, and the ability to export inventory reports to Excel and PDF. Make the UI responsive and clean, with a dark mode style by default.

Please wire up both the frontend and backend so it runs locally with environment files for each side, and make sure it works with a local database or a cloud database URI. If it helps, add a simple root command to start everything together. Look up current docs online if you need to.
