{ "prompt": "A 3D photorealistic icon for a metals and scrap market stock exchange. The scene features a bold upward-trending bar chart with 5 rising bars made of polished gold and brushed steel metallic finish, with a smooth curved trend line in dark forest green running over the bars. Scattered around the base: industrial metal scraps, steel coils, copper pipes, and metal bolts rendered in gold and silver tones. A few large shiny gold coins stacked on the right side. The overall composition is clean and centered, slightly elevated isometric view. Soft warm studio lighting with subtle shadows. Background is a plain warm off-white beige (#F0EDE6). No text. No letters. The style is identical to premium 3D financial planning social media visuals — soft diffused light, high-gloss reflections on gold surfaces, matte finish on green elements, cinematic depth with soft drop shadows.", "style": "premium 3D render, photorealistic, soft diffused studio lighting", "aspect_ratio": "1:1", "color_palette": { "primary": "#1B5E3B", "gold": "#C9A84C", "silver": "#D0D0D0", "background": "#F0EDE6", "accent_white": "#FFFFFF" }, "lighting": "soft three-point studio lighting, warm key light from top-left, gentle fill light, subtle ambient occlusion shadows", "background": "plain warm off-white beige, no gradients, no patterns", "materials": { "bars": "high-gloss polished gold metal", "trend_line": "dark forest green matte with slight sheen", "scraps
