JohnCoates/Aerial ? reverse-engineered prompt

Build me a Mac screensaver app that shows the calm, cinematic Apple TV aerial style videos.

I want it to feel like the old Aerial saver, something I can install and run on macOS, with a simple settings window where I can pick which videos to show, turn on or off things like music or info overlays if they exist, and update the content easily. Make it polished, smooth, and native looking, with the usual screensaver experience on Mac.

If you need to look up current Apple docs or best practices, go ahead and do that. Keep the code clean and make sure it works well as a real macOS screensaver project, not just a demo.
