Early-2000s TV cartoon style, thick black outlines, flat bold colours with one hard shadow tone, simple geometric shapes, playful and chunky.

LED visor, round goggles, square sunglasses, a monocle, 3D glasses The base character's pose: body and head turned about 15 degrees so the face points slightly to the viewer's right, eyes still looking at the viewer, both eyes fully visible; 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 at the viewer with a cheerful, curious expression; draw every item in that pose and perspective.

Anatomy of this character to respect: Round ear discs stick out on both sides of the head at eye level (left at x≈315-405, right at x≈680-712), so glasses arms and hat brims must sit around them. The neck is a narrow segmented metal cylinder, and the domed head top has a silver riveted center stripe.

Draw 16 glasses 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 FACE: lens centres exactly on the eyes at x=497 and x=637, y=462 (±25px), bridge over the nose at x=560, total width 40% to 120% of the 345px head (a turned head foreshortens the pair); arms may run to the sides of the head. 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 glasses pixels; everything else fully transparent. Write artifacts/glasses_01.png .. glasses_16.png and artifacts/glasses.json: an array of {"file","name","weight"} with weights summing to 100, rarer lower.
