Custom Studio Product Packshot

Create a 4:5 studio packshot from two user inputs: RIGHTS-CLEARED PRODUCT REFERENCE and BACKGROUND COLOR OR MATERIAL. Match only the product's supplied geometry, proportions, color, finish, and visible details; do not add a logo, label, feature, accessory, or claim that is absent from the reference. Place one product upright at center on the requested seamless backdrop, leaving at least fifteen percent clear space around its silhouette. Use broad high-key illumination from upper left, a soft fill from front, one narrow edge card on the opposite side, and a single grounded shadow whose direction matches the key. Allow a restrained reflection only when the user requests a reflective surface. Keep the product's front and primary material junction ultra-sharp, then let focus fall gently toward the far edge without blurring identifying shape. Make the background gradient result from light falloff rather than added graphics. No person, extra product, floating object, invented pack copy, brand substitution, performance or quality superlative, fake DSLR metadata, copied campaign, text, logo, heavy haze, harsh clipping, or watermark.
