    "prompt": "Create a premium science journal editorial cover art, landscape 3:2, edge-to-edge artwork, NO text, letters, numbers, logos, borders or watermarks. Museum-quality sculptural still-life photographed with a large-format lens; physically believable materials and light, masterful composition, restrained warm gold details with rich dark ink accents. Sophisticated contemporary research magazine, tactile cinematic art, strong silhouette readable at thumbnail size. Conceptual illustration openly labeled by publisher, not an experimental visualization. Avoid generic AI brains, robots, microchips, neon cyberpunk, stock-tech clichés, flat infographic boxes, glossy plastic, rainbow gradients. Topic: preference alignment. Two exquisitely crafted ribbons, one pale pink ceramic and one brushed warm brass, begin on separate sides then curve gracefully through a single narrow dark stone gateway, emerging as a harmonious parallel pair. Abstract sculpture rather than a literal flow chart; a poetic image of choices becoming a constraint. Muted terracotta rose studio background, dark wine-colored gateway, warm ivory and gold ribbon highlights, dramatic soft side light, fine shadows, a subtle tactile paper backdrop, confident uncluttered composition with interesting interlaced geometry.",
