yash200731-design/dashboard ? reverse-engineered prompt

Build me a clean modern dashboard web app that lets a user log in, see a main overview page, and navigate around a few simple sections like stats, recent activity, and settings.

I want it to feel polished and responsive, with a sidebar or top nav, summary cards, charts or visual widgets, tables or lists, and a nice light UI that works well on desktop and mobile. Please make it easy to extend later, and connect any simple backend API or mock data if needed so the pages actually show real content instead of placeholders.

Use the existing project setup, keep the styling consistent, and make sure it runs smoothly in development and deploys without extra fuss. If you need to check current docs for anything, look them up online.
