CHARACTER: Canvas: 1024x1024 transparent PNG.

Style: flat cartoon with bold dark outlines and simple cel shading.

Subject: one gangster monkey base with a tough, streetwise expression, three-quarter view turned to the viewer's left.

Placement: crown at y=150, eye line at y=420, chin/jaw bottom at y=690, narrowest neck at y=730. The head is 410px wide (x=307 to 717) with its bounding box centred on x=512. Because of the turn, the face centre line sits near x=490 and the far (viewer's right) side of the head is foreshortened.

Keep natural monkey proportions: rounded cranium, a pale muzzle/face patch with the mouth near y=600, and ears at the sides of the head around eye level, kept below the crown so hats can sit on top. Shoulders run off the bottom edge at y=1023. Draw a simple neutral closed mouth on the base.

No hat, no glasses, no clothing: bare furred neck and shoulders, with no collar, scarf or chain.

Output: character/base.png.

Weights file: character/weights.json with {"base.png":1}.

BACKGROUND: Canvas: 1024x1024 fully opaque PNG.

Style: flat colours or soft two-tone vertical gradients from one cohesive moody 'gangster' palette (deep burgundy, smoky charcoal, dark teal, muted gold, olive, dusty navy and similar), matching the character's flat cartoon look. No scenery, no objects, no texture, no text, and nothing that competes with the monkey in the centre (head x=307 to 717, y=150 to 730). Make 12 distinct backgrounds.

Outputs: background/bg_01.png through background/bg_12.png.

Weights file: background/weights.json, giving each of the 12 files equal weight 1. Write artifacts/base.png, artifacts/background_01.png .. background_12.png, and artifacts/traits.json: {"backgrounds":[{"file","name","weight"}...]} with weights summing to 100.
