Premium Technical Puffer Campaign: Elevated Mineral Studio Editorial

Use the uploaded product image as the exact garment reference if supplied; otherwise create a premium charcoal oversized puffer jacket with relaxed technical trousers and simple monochrome sneakers for fictional label Null Terrain. Preserve referenced jacket and trousers exactly including colors, quilting, pockets, seams, logos, fabric texture, cuffs, waistband, construction, fit and proportions. Feature an adult female fashion model seated confidently across a cluster of massive rough white mineral rocks inside a minimal neutral-grey studio, one knee raised higher on the rock while the other leg extends downward, one hand inside the trouser pocket and the opposite hand resting on the raised thigh. Add narrow sculptural sunglasses only if they do not conflict with the uploaded product. Background is a seamless grey gradient with no visible studio equipment. Use soft neutral top-front illumination that resembles diffused skylight, creating realistic rock shadows without colored effects or glow. Slight low-angle frontal camera, strong fashion-forward composition, realistic anatomy and rock interaction, crisp mineral texture, detailed technical fabric, ultra-realistic 8K campaign photography, no watermark, no unwanted text, aspect ratio 2:3.
