  "prompt": "Wide cinematic educational illustration of a natural sunset over a calm freshwater lake, viewed from shore. The Sun is very low near the horizon. The sky shows a physically plausible gradient: deep blue overhead, transitioning through pale blue and warm gold to vivid orange and red near the horizon. Thin clean atmosphere, subtle high clouds catching red-orange light, realistic water reflections, natural shoreline silhouettes. Emphasize the contrast between blue daylight overhead and red-orange direct sunset light without text, arrows, labels, logos, people, buildings, brands, or stock-photo styling. Polished science-magazine illustration, realistic but clearly illustrative, balanced composition, 16:9 hero image.",
