Build me a simple app for a menu called MenuGran that feels like a clean modern progressive web app.

I want people to be able to open it on their phone, browse the menu easily, and see items grouped in a way that makes sense, like categories and clear prices. It should feel fast, mobile friendly, and easy to read, with a nice polished look for a small business. If it makes sense, add a way to view item details and make it work well like an installable web app.

Keep it simple and practical, and use whatever structure is already in the project. If you need to check current docs or best practices, go ahead and look them up.
