myoussef-cpu/Vertex — reverse-engineered prompt

Build me a clean full stack starter app called Vertex. I want a frontend and backend that both use TypeScript, feel modern, and are easy to run and keep building on. The frontend should have a polished landing page for Vertex, a simple app layout, and at least one screen that loads data from the backend so I know everything is wired up correctly. The backend should expose a small API, return sample data, handle basic errors nicely, and be organized in a way that is easy to extend later.

Please make it feel production minded but still lightweight, with sensible defaults, environment config, and a smooth local dev setup. Add a short README that explains how to install, run, and build it, plus what each part is for. If anything important is missing, make reasonable choices and keep the codebase tidy. You can look up current docs online if you need to.
