  "prompt": "Wide 16:9 premium photorealistic educational science illustration about why afternoon air can be warmer than at solar noon. Show two matched moments of the exact same quiet suburban schoolyard from the exact same camera viewpoint, arranged left-to-right with a softly blended center transition and absolutely no divider line, frame, border, text, labels, arrows, or clock. A simple white weather post stands in the same foreground position in both moments with one large clear glass liquid thermometer mounted vertically; the thermometer has no readable numbers or writing. LEFT NOON MOMENT: one small Sun very high near the top-center, short compact object shadows, bright neutral daylight, thermometer red liquid column visibly at a moderate level. RIGHT MID-AFTERNOON MOMENT: one small Sun lower toward the upper-right, longer shadows cast away from the Sun, still bright clear daylight rather than sunset, thermometer red liquid column visibly higher than on the left. Same buildings, trees, post, camera height, and weather in both moments so the only meaningful changes are Sun position, shadow length, and higher thermometer liquid. Natural restrained colour, crisp realistic photography, premium science-magazine look, uncluttered, physically plausible.",
