In case you haven’t, you probably need to install breeze-icons via craft first (forgot to mention that, also, not entirely sure on the name of the package, it’s been a while since I installed it and am not near my dev machine right now)
I’ll look into the prefix to see if I messed up something there. I haven’t put in all that much time to get it to work standalone yet, was something I worked on literally the other day for an hour or so.
PS: Really interesting with the page title, will have to investigate that some more
