cloudreve/frontend ? reverse-engineered prompt

Build the frontend for Cloudreve and turn this starter into a polished, production ready web app.

I want a clean React interface that feels like a real product, not a template. Start with a simple landing or login screen, then a main app shell with navigation, a dashboard area, and a few sensible empty states or placeholder pages for the core user flow. Keep it responsive, modern, and easy to extend later. Use the existing TypeScript setup, make the UI look consistent, and wire up the basic app structure so it’s ready for real features and backend data.

If you need to look up current docs or best practices for anything, go ahead and check online.
