CodectaFrontend3/Facturacion_next — reverse-engineered prompt

I want this turned into a simple, polished invoicing web app in Next.js. Keep it front end focused for now, using mock data or local state so it works right away without needing a real backend.

Make it feel like something a small business could actually use. I’d like a clean home screen, a page to create an invoice, and a page to view saved invoices. On the invoice form, let me add client details, invoice number, date, line items, quantity, price, tax, and show the subtotal and total automatically. It should be easy to edit and remove items before saving.

For the invoices list, show the main details clearly and make it easy to open one and review it. Add a simple responsive layout so it looks good on desktop and mobile. Use a modern, professional style, not too flashy.

If there’s nothing already built yet, start from the existing app and create the basic structure and pages. Look up current Next.js docs online if you need to.
