    "prompt": "Premium scientific journal cover art, landscape 3:2, no text, numbers, logos, watermark or borders. A breathtaking editorial still-life with gallery-grade sculptural material, warm golden details, cinematic but natural illumination, believable shadows and highly tactile surfaces. Intelligent contemporary magazine art direction, refined color palette, memorable composition that reads at thumbnail size. Openly disclosed conceptual art, never an actual experiment or graph. Avoid flat diagrams, sci-fi brains, robot heads, computer chips, neon networks, cheap gradients and generic stock imagery. Topic: evaluation beyond a single leaderboard. A large impeccable optical glass prism stands among a few parallel translucent measurement planes on a matte ivory stone base. A soft shaft of white light passes through and separates into three restrained muted teal, amber, and coral light bands landing in different areas; NOT a full rainbow. Composition shows multiple perspectives and uncertainty, elegant light optics, immense negative space with subtle cool-gray backdrop, fine gold metal edges, museum still-life, pristine glass caustics, strong artistic focus. No charts, rulers or labels.",
