omanandswami2005/PathGenie ? reverse-engineered prompt

Build me a simple full stack web app called PathGenie that helps people create, view, and manage paths or routes in a clean, easy way.

I want a nice client side interface where someone can add a new path, see a list of saved paths, open one to view its details, and remove or update it if needed. The app should feel modern and straightforward, with good spacing, clear buttons, and a responsive layout that works on desktop and mobile.

Please also build the backend so the client can save and load data properly, with basic API routes and simple error handling. If you need to look up current best practices or docs online while building, go ahead. Make it work as one complete project, with the frontend and server connected and ready to run.
