Important notes:

Save vs publish — this is the key tension. Right now the flow forces a binary: publish or discard. But users naturally want a third state: "I'm done for now, save my draft, I'll publish later."

Discard isn't really "throw away my work" — it's closer to "revert to the last published version", which is a much more meaningful and specific action. That's a different mental model entirely.
