Deepanshv/analytics-dashboard ? reverse-engineered prompt

Build me a simple analytics dashboard web app with a clean modern feel.

I want a homepage that shows key metrics, a few summary cards, and some basic charts or visual sections for things like traffic, revenue, and user activity. Make it feel like a real dashboard people could use to quickly understand what is going on at a glance. Add a nice responsive layout so it works well on desktop and mobile, and use the existing starter structure in the project to get it running smoothly.

Please keep the design polished but straightforward, with reusable components where it makes sense. If you need to check current docs online for anything, go ahead. Also make sure the app has sensible placeholder data so it looks complete even before real analytics are connected.
