    "prompt": " Clean, humorous still-life photo of a large brass speaking trumpet (megaphone-style) placed on a crate at the side of the stage, next to a handwritten placard: “ANALOGUE PA — PROJECT YOUR SPIRIT.” Include a mic stand nearby that is clearly unused, reinforcing the anti-modern gimmick."
