Prompt
An empty performance stage, dark steps, angled magenta and indigo panels on both sides with a fine halftone dot. Two volumetric beams from above, magenta on the left and cyan on the right, splitting through haze. A row of glowing vertical bars rises like an equalizer just behind center. A large deep-violet field in the middle is left empty for a title to be added later. Print-poster finish, clean edges, hard contrast, only magenta, electric blue, and near-black. Wide frame, the stage in the lower third, open space above. No letters, numbers, fine print, watermark, or garbled type.
