Clean bold cartoon, thick black outlines, flat colours with one soft shadow tone, glossy highlights, warm playful palette. beanie, backwards cap, bucket hat, beret, tiny crown The base character's pose: facing straight at the viewer, both eyes level and looking at the viewer, head centred left to right; framed head and shoulders: the top of the head near y=210, the neck meeting the shoulders near y=740, both shoulders and the upper chest in the picture and running off the bottom edge; the arms are down and out of view, nothing in front of the chest; extra detail from the creator: looking straight at the viewer with a relaxed, confident expression; draw every item in that pose and perspective.

Anatomy of this character to respect: Cat ears stick up at the top corners of the head (around x 305-420 and 600-720, up to y≈245), so hats must sit between or over them. Wide fluffy white cheek ruff extends out to the sides of the head at eye-to-chin level; the neck is fairly narrow (x≈432-598) under a rounded chin.

Draw 16 hat variants as separate 1024x1024 RGBA PNG layers for a generative PFP collection, matching the attached base character's rendering style, lighting and line weight exactly. Colours and materials come from the request and the item itself (felt, leather, brass, wool, glass, fabric), NOT from the base character's skin or bone: an item must never look made of the character's own surface.

Make the 16 variants clearly different from each other in shape, material and colour, covering the full range the request names.

Placement: WORN ON THE ATTACHED BASE, at eye level in the base's own facing and perspective (never from below): the hat sits DOWN over the top of the head so its band and lower edge cover the upper cranium; never show the inside, underside, lining or opening of the hat, and never perch it on top with head visible under the brim.

The hat's lower edge wraps the crown and overlaps the top of the head, so its lowest pixel falls between y=260 and y=438 (crown is at y=245, eye line at y=468); centred on x=512; brims may extend past the 440px head. A hat whose lowest pixel is above y=260 looks like it is floating and is wrong.

Never squash, fold or bend a hat sideways to fit the picture: a hat too tall for the space above the head (from the top edge down to the crown at y=245) is drawn shorter, never cropped by the top edge.. This layer is painted IN FRONT of the character, so never draw anything that should be behind it (the back of a hood, the back of a chain, the back of a hat brim behind the head): it would show in front. Only the hat pixels; everything else fully transparent.

Write artifacts/hat_01.png .. hat_16.png and artifacts/hat.json: an array of {"file","name","weight"} with weights summing to 100, rarer lower.
