I'm gonna take this as a starting point to look at the JavaScript interface. It's possible I break a couple of things as we discussed already.

Also

arizona.subscribe("reload", () => {
  location.reload();
});

should probably be internal to arizona.js so we get rid of an extra .js 😄

(or maybe I can't, so easily, looking at the code, but I'm sure there's a way to pass options to not have this file isolated - it seems to be there only to make a choice on the Erlang side of things)

This piece of code is from arizona-live-reload.js, so it's a development thing. It should be optional. We have not defined/discussed an interface for the live-reload, and this file may grow (or not). I don't see it as a problem right now. We could change this later.

Yeah, I saw it being called separately in the code, so I won't touch it for now.
