Use Case Music Box: Prompt Pin Cylinder

Create a single polished gallery image for a new GPT Image 2 use case titled Use Case Music Box: Prompt Pin Cylinder. Show a macro product photograph of a transparent hand-cranked music-box mechanism on a plain workbench, not a contact sheet, not a 2x3 board, not a route map, not a chessboard, and not a tray. A brass pin cylinder is wrapped with a long punched paper prompt roll; the holes and raised pins encode prompt clauses that strike comb tines labeled for image controls. Tiny fictional thumbnail windows appear as repeating motifs around the cylinder, showing the same invented ceramic moon-lantern object in rhythmic variations. The mechanism tests GPT Image 2 for planned visual rhythm, repeatable motif identity, readable micro-labels, and controlled variation across a circular sequence. Readable labels should include Wind Brief, Pin Clause, Comb Render, Motif Repeat, Silence Mask, Tempo Crop, Label Chime, Variation Click, and Final Tune. Output format: premium macro photograph of a mechanical music-box prompt instrument with brass cylinder, punched ivory paper, glass cover, crisp readable labels, soft neutral lighting, no hands, no logos, no real brands, no real people, no copyrighted characters, no political content, no dangerous instructions, no gore, no sexual content, no living artist style imitation.
