PRODUCT AS VISUAL TRUTH
{{subject}}
Preserve exact silhouette, proportions, component placement, material boundaries, packaging shape, and any user-supplied brand marks. Do not invent labels or redesign the product.
SET AND SURFACE
{{scene}}
Define the support surface, background transition, foreground accents, atmosphere, and scale cues. Keep the set subordinate to the product.
ART DIRECTION AND LIGHTING
{{style}}
Use intentional key, edge, gradient, and bounce lighting to reveal material properties. Control reflections so glossy, metallic, glass, fabric, and translucent surfaces remain physically plausible.
DELIVERY CONSTRAINTS
{{constraints}}
Reserve deliberate negative space for copy without generating text. Keep the complete product inside frame, edges clean, perspective credible, and contact shadow grounded. Produce one hero composition with premium commercial retouching.
