AshishS-1123/ClickUp-Clone ? reverse-engineered prompt

Build me a ClickUp style project management app that feels polished and easy to use.

I want users to be able to sign up and log in, then create their own workspaces and switch between them. Inside each workspace, they should be able to organize things with spaces, folders, and lists, then add tasks with priorities and statuses. Please make the flow simple so it feels like a real productivity tool, not a demo.

Use a modern web app setup, with a separate client and server, and store the data in MongoDB. If you need to check anything from the latest docs while building it, go ahead and look it up online. Also include some basic sample data so I can see the app working right away after setup.
