Ice-Storm1/Velkron — reverse-engineered prompt

Build me a small desktop app called Velkron using the existing Tauri, React, TypeScript, Vite setup. Right now it can be a polished starter app, since I mainly want the foundation finished and not just the default template.

Make it open to a clean modern home screen with the Velkron name, a simple navigation area, a welcome section, and a settings page where I can toggle light and dark mode. Use Tailwind for the styling, keep everything neat and easy to change later, and make sure it runs as both the web dev app and the Tauri desktop app.

Please remove any placeholder template content, organize the React components clearly, and keep the UI simple but finished enough that it feels like a real app. If you need exact Tauri or Vite details, look up the current docs online.
