bhargavptl8/Admin-Dashboard-MUI ? reverse-engineered prompt

Build me a responsive admin dashboard in React that feels clean and modern, using MUI for the layout and components, React Icons for the icon set, and React Router for navigation between pages.

I want a main dashboard screen with a sidebar, top bar, and a few useful admin sections like overview, users, products or orders, and settings. It should look good on desktop and still work nicely on smaller screens. Please make the navigation smooth, the layout organized, and the pages easy to swap between without refreshes.

Use sensible placeholder content where needed so the app feels complete, and keep the design polished and easy to extend later. If you need to check current docs for MUI or routing details, go ahead and look them up online.
