 ## What this solution does
 This repository contains the front-end for the ZUGFeRD Mustang UI, a Vite + React + TypeScript application styled with Tailwind CSS and shadcn/ui components. The new automation scripts streamline getting from source code to the generated production HTML that ships in `dist/`. Each script installs the required Node.js dependencies (if needed) and triggers the framework's production build so you always end up with the final static assets.
