Create one premium commercial product photograph, vertical 4:5. Fictional luxury product: an unlabelled sculptural amber-glass perfume bottle with a substantial brushed champagne-metal rectangular cap, no brand or logo. Place on a dark charcoal stone pedestal, warm cream architectural studio background with generous negative space. Soft key light from camera-left and subtle right rim lighting, controlled sophisticated reflections, visible glass thickness and amber liquid, polished yet believable materials, refined charcoal and cream palette, photographic detail. Single beautiful product, no extra promotional text, no labels, no watermark. New fictional sample, no uploaded product identity or packaging reference is provided.
