This is an excellent sample. UI looks fantastic. Tested on WPF and MAUI Android (landscape works as well 😃), everything seems to be functioning correctly. My feedback is focused on comments which applies to all implementations.

Looks great @duffh! I was able to test it with the .NET sample viewer. I've left some minor comments. Thanks!
