Using the uploaded product photo, generate a high-resolution mockup with these exact specifications: [COMPOSITION]: The product must be the ONLY object in the frame. Maintain the original product's angle, position, and focal length. NO props, NO kitchen tools, NO ingredients, and NO extra items. [LIGHTING]: Apply directional, hard 'Kitchen Spotlight' lighting to create deep, dramatic shadows and bright, glistening specular highlights on the edges. [BACKGROUND]: A completely empty, solid, dark moody matte background (deep slate or dark charcoal). No textures or environmental elements. [SHADOW]: A sharp, dense contact shadow directly beneath the jar, adding a sense of weight and 'Modern Grit'. [PRODUCT INTEGRITY]: STRICTLY PRESERVE the product's original surface. DO NOT add any new text, logos, graphics, or branding. The product must remain exactly as it appears in the uploaded photo, with all original labels and artwork 100% intact. [MOOD]: Premium, minimalist, chef-driven, authentic and bold 'Modern Grit' aesthetic.
