    "prompt": "One continuous four-second shot in an empty black-box theater. A fictional adult performer wearing a plain silver face mask and a fitted indigo rehearsal suit holds one long unprinted ivory ribbon. Beat one: the performer steps forward and draws one low horizontal ribbon arc. Beat two: they pivot once and lift the same ribbon into a vertical spiral. Beat three: they stop in a balanced stance while the ribbon settles behind the right shoulder. The camera makes one smooth waist-height semicircle from front-left to front-right. Preserve the same mask, body proportions, suit, ribbon length, hand count, stage geometry, movement direction, and lighting throughout. Use natural weight transfer and physically believable cloth motion. Synchronized audio: three soft footfalls, ribbon movement through air, and restrained room reflections. No cuts, no extra people, no dialogue, no music, no readable text, no logos, no brands, no products, no advertising, no watermark.",
