    "prompt": " Studio photo of a close-up human hand index finger touching the surface of a clear glass bowl of water on a lab bench. Minimalist “science” props: latex glove box in the background, a labeled beaker, and a cheeky printed checklist titled “Study Phases” with Phase One checked off. Lighting crisp and clinical, emphasizing ripples where the finger meets the water."
