Cloduar/Relacion-de-costo ? reverse-engineered prompt

Build me a simple desktop app for keeping track of product costs and sales in a small business.

I want to be able to manage products, raw materials, recipes, purchases, sales, and product types from one place, and have the app calculate the cost relation for each product automatically. It should save everything locally in a SQLite database, let me add, edit, delete, and search records, and show a clear history of purchases and sales. I also want a screen that helps me see the cost breakdown for a finished product based on the ingredients or materials used.

Make it easy to use, clean, and practical for someone who just needs to track costs and profitability without a complicated setup. If anything is unclear, use sensible defaults and look up current docs online if you need to.
