    "prompt": "Commercial-grade studio jewelry-on-model product photo for e-commerce.\n  \n  MANDATORY WEAR / PLACEMENT RULES (HIGHEST PRIORITY):\n  - The jewelry MUST be shown being worn on a real human body part in a natural, physically correct way.\n  - Do NOT show the jewelry in a box, on a table, floating in the air, isolated on a plain background, or as a packshot.\n  - The jewelry must be in skin contact or realistic fabric contact:\n    • bracelet or bangle: wrapped around a wrist or forearm, following the wrist curvature and gravity\n    • ring: around a finger, touching skin, sized correctly\n    • earring / hoop / stud: attached to the earlobe or cartilage, following ear curvature\n    • necklace / chain / pendant: resting on chest / neck / collarbone with correct drape\n    • watch-like piece: worn on wrist like a watch\n  - The camera framing MUST include the relevant body area (wrist, hand, ear, neckline, etc.) clearly. No full-body shot.\n  \n  CRITICAL PRODUCT ACCURACY (EQUAL PRIORITY TO WEAR RULES):\n  - The jewelry in the final image MUST MATCH the provided jewelry reference images 1:1.\n  - Copy the exact design, geometry, thickness, proportions, stone shape, number of stones, engravings, clasp/hinge/lock type, and construction details.\n  - Copy the exact material and finish: metal color (yellow gold / white gold / silver / rose gold / etc.), surface texture (polished / brushed / hammered), gemstone color and transparency, and any pearls or inlays.\n  - Do NOT redesign, stylize, simplify, add extra gems, change metal color, scale the stones, or alter engravings.\n  - The jewelry reference images are the single source of truth. If any text instruction conflicts with the reference jewelry, ignore the text and follow the jewelry images.\n  \n  REALISM TARGET:\n  - The jewelry must look like a solid physical object interacting with skin: correct physical scale, believable placement, natural deformation of soft tissue where it touches, correct shadows and reflections.\n  - Show accurate reflections, specular highlights, micro-scratches, sharp metal edges, gemstone sparkle, and soft contact shadows where jewelry touches skin or fabric.\n  - Lighting: high-end studio beauty lighting with soft falloff and realistic shadows. No CGI glow, no toon shine.\n  - Skin: high-end beauty photography quality — visible pores and texture, slight tonal variation. Not plastic, not AI-smoothed.\n  - Hands / wrist / ear / neckline presentation should look like a luxury jewelry catalog photo.\n  \n  AESTHETICS / COMPOSITION:\n  - Tight professional crop on the body area that showcases the jewelry (close-up wrist, hand near face, ear/neckline portrait, etc.).\n  - Neutral, unobtrusive background with slight depth of field / blur to feel like a real studio or editorial environment.\n  - Makeup and styling should be minimal, timeless, and commercially usable — no fantasy styling, no dramatic colored gels.\n\n  \n  OUTPUT INTENT:\n  - This image will be used as an e-commerce \"on-model\" listing photo to prove how the piece looks when worn. Standalone product renders are NOT acceptable.\n  \n  \n    \n  MODEL / POSE (NO REFERENCE MODEL PROVIDED):\n  - Generate a realistic human model wearing the jewelry naturally.\n  - Pose should be relaxed, elegant, and product-focused, like luxury e-commerce photography.\n  - The jewelry must be clearly visible and readable for an online product listing.",
