aditya23gautam/neuronest ? reverse-engineered prompt

Build me a simple app called Neuronest with a clean, modern feel and a calm brain and learning themed design.

I want the project set up so I can open it and see a polished starting experience, with a home screen, a clear navigation area, and a few placeholder sections that make the app feel real even if the content is basic for now. Please make it look good on desktop and mobile, and keep the code organized so it is easy to expand later. If you need to check current docs online for the best way to set things up, go ahead and do that.

I mostly want a solid first version I can run right away, with sensible defaults, good spacing, and no rough edges. If anything about the project is unclear, choose the simplest option that makes the app feel complete.
