aolose/webClip — reverse-engineered prompt

Build me a simple online tool that lets someone create an iOS web clip profile from a web page. The user should be able to open the site in a browser, enter the details they need for a web clip, upload or set an icon, and download the generated mobileconfig file.

It should work locally first, serving a small web interface and generating an unsigned web clip file by default. Also make it possible to run it with certificate, private key, and chain files so the generated web clip can be signed. Keep it lightweight and easy to deploy on an Ubuntu server as a background service.

Please include basic instructions for building from source, running it locally, running it with signing certificates, and installing it as a service. The end result should feel like a clean demo site where someone can quickly make an iPhone web clip without knowing the technical details.
