The attached cat.png is the base character of a generative cat PFP collection: flat vector, thick navy outlines, warm limited palette (coral, teal, mustard, lavender, cream, navy). Match that style, line weight and palette exactly. All outputs are 1024x1024 RGBA PNGs.

Draw 12 jumpers (sweaters, hoodies, shirts, a suit, a lab coat, a hawaiian shirt, a tracksuit top, a cardigan, a turtleneck, a vest, a kimono, a football shirt) as transparent overlay layers that clothe the cat's shoulders and chest exactly as drawn in cat.png: the body spans x=148..876 and y=760..1024, the neck line sits at about y=770 under the chin.

The garment must cover the body outline cleanly with its own outline, leave the head, face and ears untouched, and reach the bottom edge y=1024. Only the garment pixels, everything else fully transparent. Write artifacts/jumper_01.png .. jumper_12.png and artifacts/jumpers.json: array of {"file","name","weight"} with weights summing to 100, rarer lower.
