Biff tutorial: build a chat app with Clojure

Excellent project, I love the xtdb/htmx stack, and wanted to experiment with it myself. Maybe I'll give biff a try first!

I was going to ask why the tutorial mentions using rum to render components, but then also mentioned using htmx, since the latter seems like it should be sufficient. But a quick perusal of the code suggests rum isn't used after all. Why does the tutorial still mention that?

Rum is used throughout, though mostly via middleware[1], so you (almost) never see any calls to `rum.core/render-static-markup`. But all of the hiccup-style data structures (`[:div "foo"]`, etc) do get rendered by Rum.

htmx doesn't render anything on the backend; rather it gives the frontend more ways to interact with the backend. e.g. say you make an inline form--htmx gives you the ability to display/submit that form without refreshing the entire page, but all the html that's sent to the frontend is still getting rendered first by Rum.
