  "prompt": "Use case: stylized-concept. Asset type: premium landscape scientific editorial cover for Auturnal. Subject: A layered geological cutaway of ivory stone and dark teal strata, an amber seismic wavefront rises toward a few precision surface sensors, elegant restrained conceptual geophysics. Museum-quality sculptural scientific art, exceptional controlled detail, credible physical forms, rich natural textures and tasteful negative space. Restrained warm ivory, amber copper and deep petrol colors, confident cinematic daylight, wide 3:2. No typography, text, logo, watermark, data chart or imitation of experimental evidence; no neon network cliches. A beautiful concept illustration with one coherent scientific focal idea.",
