100security/dsf ? reverse-engineered prompt

Build me a simple web page for Dork Search Files that lets someone run Google dork searches to find public files on the web.

I want a clean dashboard where I can enter a search term, choose file types like PDF, DOCX, XLS, and TXT, and then build the right Google search for me. It should also let me add my Google API key and Programmable Search Engine cx id, then show the results in a clear list with title, link, and a short snippet. Make the page easy to use, responsive, and visually polished, with a security style look that matches the idea of the project.

If you need anything unclear, look up the current Google docs online and keep the setup simple. Please make it work as a single HTML page if possible, with all the main controls and results on one screen.
