IPTVCloud-app/EPG — reverse-engineered prompt

Build me a simple Python utility for IPTVCloud.app that keeps an IPTV program guide up to date.

It should read the existing stream and content JSON data, check which streams are working, generate or refresh thumbnails, and produce clean EPG output that can be used by IPTV apps. I also want it to format the XML nicely and split large XML files if needed so they’re easier to serve or upload.

Please make it easy to run with one command, with clear console messages so I can see what happened, what failed, and which streams are offline. Keep the data files simple and editable by hand. If a thumbnail or stream fails, don’t crash the whole update, just log it and continue.

There isn’t much documentation, so keep the implementation straightforward and add a short README explaining how to install, configure the JSON files, run the update, and where the generated guide, status data, and thumbnails end up.
