blasty8084/pentacloud ? reverse-engineered prompt

Build me the PentaCloud app as a polished full stack web app with a separate frontend and backend, ready to run locally and deploy cleanly.

I want a simple modern interface that feels finished, with clear navigation, good spacing, and responsive behavior on desktop and mobile. The backend should expose the main app logic through a clean API, and the frontend should connect to it smoothly and handle loading, empty, and error states well.

Please make the project easy to set up from scratch, include sensible defaults, and keep the code organized so it is easy to extend later. If anything is unclear, use the existing project files as the source of truth and look up current docs online if you need to. Also make sure the deployment setup works well with the repo structure so I can get it online without extra fuss.
