CHARACTER: Canvas 1024x1024, transparent PNG. Draw ONE friendly 1930s rubber-hose Cuphead-style character (e.g. a cheerful cup- or mug-headed toon with pie-cut eyes and rosy cheeks), facing straight at the viewer, both eyes level and looking at the viewer, head centred on x=512.

Template: crown y=210, eye line y=425 (eyes at about x=450 and x=574), chin y=665, head 350px wide (x=337 to 687) at the cheeks, natural toon proportions about 1.3x taller than wide, domed top, narrowing jaw. Any cup handle or straw stays small and does not exceed x=300 to 724 or rise above y=150. Neck narrowest at y=700, neck about x=467 to 557, meeting the shoulders at y=740; bare shoulders and upper chest run off the bottom edge.

Arms down and out of view, nothing in front of the chest. NO mouth drawn (smooth skin where the mouth goes, centred near x=512, y=575). NO clothing, collar, scarf or shirt; NO chains or necklaces; no hat, no glasses, no held item.

Leave space where the mouth would go clear.

Output: character/base.png.

Weights file: character/weights.json with {"base":100}.

BACKGROUND: Canvas 1024x1024, opaque PNG, full bleed. Paint 12 different retro 1930s-cartoon platformer game levels in the Cuphead style (hand-inked outlines, watercolour-painted backdrops, sepia film grain): e.g. carnival boardwalk, haunted forest, candy land, cloud kingdom, sunken pier, steamboat river, inkwell isle hills, casino, junkyard, snowy peaks, toy factory, desert pyramid.

Show platforms, floating blocks or ledges in the side-scroller manner, but keep the centre region x=300 to 724, y=150 to 1024 calm and lower in contrast so the character reads in front; no characters, enemies or text.

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

Weights file: background/weights.json giving each file weight 1. Also write artifacts/base_b.png and artifacts/base_c.png: two more takes of the SAME character on the SAME template and pose, each a SEPARATE, FRESHLY GENERATED image (run the image tool again for each one; never copy, edit, recolour or re-save base.png), so that if one comes out too big, too small or off-centre another may fit.

Write artifacts/base.png, artifacts/background_01.png .. background_12.png, and artifacts/traits.json: {"backgrounds":[{"file","name","weight"}...]} with weights summing to 100.
