Can I customize the Order that Facets Appear in?

Correct! Those are static filters. Since static filters do not depend on the query itself and are defined client-side, on the page, you can customize everything about them - their order, labels, etc. Facets, on the other hand, are returned by the server and depend on the query, so we haven’t yet created a mechanism for controlling the order in which they appear. It’s on the roadmap, though!
