Cinematic Romcom Scene on a Carousel with Identity Lock

A complex, highly constrained JSON prompt for Nano Banana Pro designed to generate an ultra-photorealistic cinematic scene of a couple on an indoor carousel at night. It mandates strict identity locking based on two uploaded reference images, specific camera settings (35mm, f/2.0), warm tungsten lighting, and detailed constraints on pose and environment to achieve a romcom aesthetic.

The female sits on the neighboring horse, leaning slightly toward him, smiling back warmly. Their faces are
