pxpiyush/quantn — reverse-engineered prompt

I want you to turn this repo into a clean, polished web app starter that feels like a real product instead of an empty template. Make it responsive and modern, with a nice home screen, simple navigation, and a couple of example screens or sections so I can see the pattern for building more. Use reusable components, keep the styling consistent, and make the overall experience feel smooth and finished.

Please include the basics people expect, like loading states, empty states, error handling, and sensible defaults for forms and user interactions. Keep the code easy to follow in TypeScript and organize it so someone can extend it without digging through a mess.

Also make sure it runs cleanly locally, add a small amount of test coverage for the main user flow, and replace any placeholder content with something presentable. When you are done, update the README so it clearly explains what the app is, how to start it, and what parts are meant to be edited first. You can look up current docs online if needed.
