In an FSE theme like Twenty Twenty Four, you can have multiple header patterns. So for instance you have the default one with one row, and one that has two rows with a utility nav at the top, etc.
My question is, how do you swap header patterns globally? I know I can edit the default header template part, and I know I can change the header on a per-template basis, but what I want to do is to have multiple patterns for the header, and to choose which one is the default. That way I don’t ruin the original default one.
Ideally I’d have half a dozen or so to show a client, they pick the one they like, I make a couple of clicks in the Editor and it’s applied everywhere.
