yagolorenzi/erp-sistema ? reverse-engineered prompt

Build me a simple business management web app in Portuguese for a small company.

I want one clean dashboard where I can see the main areas of the company at a glance, like sales, customers, products, stock, invoices, and finances. It should feel like a real ERP home page, with a sidebar or top menu to move between sections, summary cards with numbers, a recent activity area, and forms or tables for adding and viewing records.

Keep the design modern, responsive, and easy to use on desktop and mobile. Use realistic sample data so it looks ready to demo right away, and make sure the pages or sections feel connected, even if it is still a front end first version. If you need to look up current best practices or docs online, feel free to do that. Please make it polished, professional, and suitable to show a small business owner.
