Important Notes

This is a static HTML5 UI template. It does not include backend data processing, server-side form submission endpoints, or database integration. It serves as a powerful frontend generator that outputs the HTML code you can connect to your own backend (e.g., PHP, Node.js, Python) or a third-party form handler.
