Luxury 3D Fashion Product Showcase

Create a premium square 3D fashion product showcase featuring exactly 9 main fashion items in a clean floating luxury composition: 1 black baseball cap on the left, 2 black-and-beige chunky luxury sneakers on staggered stone plinths, 1 black football jersey with gold trim and number 10, 1 white football jersey with black-and-gold trim and number 7, 1 metallic black-and-gold wristwatch floating in the center, 1 pair of black sunglasses with beige/gold frame on a marble cylinder, 1 black leather duffel bag with a vertical beige-and-gold stripe at the bottom left, 1 black-and-beige structured designer backpack on the right, and 1 pair of polished black leather dress shoes on a round black pedestal at the bottom right. Use color_palette with realistic leather, fabric, metal, rubber, and marble textures. Arrange the objects at different heights on cylindrical black marble, white marble, and dark stone podiums, with some items floating as if weightless. Background: dark charcoal studio wall with a soft glowing golden semicircle arch behind the jerseys, warm rim lighting, glossy reflections, subtle shadows, and floating decorative geometric accents including 3 gold spheres and 3 small gold polyhedrons. Style: high-end product advertising render, photorealistic 3D, cinematic lighting, crisp focus, luxurious boutique display, symmetrical but dynamic composition. Customize the jersey text details with black_jersey_number and white_jersey_number; include small crest-like badges and star details but no readable brand names or logos. Use aspect_ratio.
