  "prompt": "Wide cinematic educational science illustration about testing an evaporation explanation. In a sunlit schoolyard after rain, a shallow puddle on dark pavement is visibly smaller than the darker damp outline around it. Nearby on a simple outdoor science table are two identical shallow clear trays containing equal amounts of water; one tray is in gentle airflow from a small generic desk fan while the matching control tray is outside the airflow. A ruler and simple digital scale sit nearby as measurement tools, but no readable numbers or text appear. Show warm afternoon light, realistic water reflections, subtle breeze in nearby leaves, and a careful fair-test atmosphere. Emphasize observation, controlled comparison, and measurement through the composition rather than labels or arrows. Polished science-magazine illustration, realistic but clearly illustrative, balanced 16:9 hero image, no children, no brands, no logos, no watermark.",
