Generate Trivia Questions for a Themed Pub Quiz Round

You're running the quiz and you need a themed round that doesn't have everyone either bored or baffled. This writes a complete round on your theme, be it 90s music or world geography, with the difficulty ramped so the easy ones warm the room and the hard ones decide it. You walk into the pub with a finished round and answers, not a panic.
