DolevLu/odedthemapper ? reverse-engineered prompt

Build me a polished Next.js app for a project called odedthemapper.

I want a simple, modern site that works well on desktop and mobile, with a clean landing page, a few basic sections, and a nice looking layout that feels finished rather than like a starter template. If it makes sense, include a place to store and read app data with a database setup, and make sure the app is ready to run locally and deploy easily. There’s also an Android folder in the repo, so if you can keep it friendly for a mobile app wrapper too, that would be great.

Please make the homepage useful out of the box, with sensible default content, responsive styling, and good empty states. Keep the code organized and easy to extend later. If you need current docs for any Next.js or mobile integration details, look them up online and follow the latest recommended approach.
