  "purpose": "One sponsorless 3×3 shirt texture atlas. Official brand logos are rendered separately in the game. No bitmap pixel editing was used.",
  "prompt": "Use case: product-mockup. Create ONE production texture atlas for a football club management game: a precise 3 by 3 grid of nine isolated men's premium football SHIRTS, front view, no person, no mannequin. Square image. Each square cell has identical composition: collar around y=12% of cell, shirt hem at y=91%, shirt torso x=29% to 71%, shoulder and short sleeves x=10% to 90%. No cell borders or labels. White clean studio background, soft minimal contact shadow. All shirts MUST have absolutely NO logos, letters, numbers, branding, badges or sponsor, leaving front chest and centre belly completely clear for runtime official logo overlays. Top row is Manchester United inspired rich red HOME proposals: first classic red with thin black V collar and tonal woven vertical texture, second red round collar with subtle tonal chevron knit, third red polo collar with tone-on-tone geometric fabric. Middle row is ivory/cream AWAY proposals: first thin burgundy collar and faint tonal vertical knit, second bone white with very subtle muted burgundy side seam panels, third warm pale grey with woven texture and black neck trim. Bottom row is deep navy THIRD proposals: first navy with understated red collar edging, second charcoal-navy with very faint woven diagonal stripes and ivory trim, third dark midnight navy with tonal jacquard and muted red side seam. Professional high resolution adidas-style modern kit materials, realistic fine fabric, natural garment folds and detailed stitching, symmetrical straight garment silhouette. No shoulder stripes as the supplier branding will be applied separately. Keep torso upper and middle chest unobstructed. Crisp expensive official-store product photography, not illustration. Deliver the atlas as one square image with uniform cells, generous clean white margins between silhouettes."
