ArikusumaWardana/tisgumi-website ? reverse-engineered prompt

Build me a modern website for Tisgumi that has two parts, a public landing page and an internal dashboard for staff. The public site should feel clean and inviting, with a hero section, about section, features, working hours, testimonials, and a menu section that works well on both desktop and mobile.

For the internal side, I want a secure admin area where staff can manage products, customers, orders, pricing, and admin users, plus generate invoices automatically. It should include login and role based access, so only the right people can see the dashboard. I also need PDF export for invoices and data so staff can download and share them easily.

Please make it polished, responsive, and easy to use, with a restaurant focused look and feel. If you need to check current docs for any libraries or best practices, go ahead and look them up online.
