AI Summary: Implement support for both single products and products with variants in a Vue.js 3 frontend and FastAPI backend e-commerce application. This involves adding a checkbox to distinguish between product types, updating the UI to handle variant management, modifying the backend API and database models to accommodate both types, and ensuring proper validation and data handling throughout the application. The changes must be reflected in the product catalog and shopping cart components.
