Soumya-0x000/node-viewer ? reverse-engineered prompt

Build me a clean Next.js app called Node Viewer.

I want a simple web app where I can view and inspect a set of nodes in a friendly way. The main screen should feel polished, work well on desktop and mobile, and make it easy to see the node data at a glance. If it makes sense, include a basic way to switch between nodes and see more details for the selected one.

Keep the design modern and minimal, and use the existing app structure in this repo. Make sure the page loads fast, looks good out of the box, and the code is organized in a way that is easy to extend later. If you need to look up current Next.js docs online, go ahead.

When you are done, I should be able to run the app locally and see a complete working first version, not just a placeholder page.
