Thanks for the time and effort you’ve put into making this! :D
Do you have an example of where the wide cover image actually gets shown?

Well, Itch says it's used when a game is featured on the home page, but I don't think I've ever actually seen it in action. I don't always add that one to my games (mostly because I'm not ever expecting a feature on the Itch home page), but I figured I'd keep the template for it in this set for completeness.
