Canvas 1024x1024 RGBA PNG, transparent except the item. Match the base exactly: cartoon storybook style, medium dark-brown outlines, flat fills, soft cel shading. Facing three-quarter-left, so draw every necklace in that perspective.

The front loop's lowest point is shifted toward the viewer's left, around x=480. The near (viewer's left) strand is longer and more visible; the far strand curves tighter around the neck on the right.

Theme: Garden Gnome. Make 12 clearly different variants: white-and-yellow daisy chains, a buttercup chain, mixed wildflower garlands, a lei-style flower necklace, twisted jute or hemp rope, a braided rope with a wooden or acorn toggle, a rope with a small clay toadstool or snail-shell pendant, a clover chain, a vine with leaves and berries, and a rare golden-rope variant with a glowing mushroom charm.

Materials come from petals, stems, rope fibre and wood, never peach skin tones.

Placement: the necklace wraps the neck base at y=465..485. The neck spans x=400..650 at that height, centred on x=500. The necklace drapes with weight onto the upper chest.

Keep all pixels within x=330..700 and y=440..585. Nothing may go below y=585, because the raised hand (x=310..490, y=590..760) is drawn under this layer and must not be covered. Never draw over the chin, jaw (bottom edge at y=445) or nose.

The back of the necklace is hidden behind the neck: draw only the front arc between the two sides of the neck, ending where it tucks behind the neck at about x=405 and x=645 around y=465. Draw only the item: no clothing, collar or skin.

Outputs: artifacts/neck_01.png .. artifacts/neck_12.png, plus artifacts/neck.json, an array of {"file","name","weight"} with integer weights summing to 100. Common daisy and rope chains get 10–12 each; the golden rope with the glowing mushroom gets 2–3. Write artifacts/neck_01.png .. artifacts/neck_12.png and artifacts/neck.json: an array of {"file","name","weight"} with weights summing to 100, rarer lower.
