Style: bold cel-shaded 1980s disco-glam cartoon, thick black outlines matching the base, flat fills, two-tone shading, crisp white glossy highlights on lenses and frames.

Pose: head three-quarter right, chin raised, eyes looking just past camera; draw every pair in that perspective.

Placement: viewer's-left lens centred on x=510,y=500 and viewer's-right (far) lens on x=675,y=500 (±25px), the far lens foreshortened narrower; bridge over the nose at x≈590,y≈495; total frame width 136-408px (40-120% of the 340px head), keep all pixels inside x=386-794, y=374-626 except the near temple arm, which runs back from the left hinge toward the ear at about x=350,y=590 and must stop above the hoop earring (y<620).

Do NOT draw the far temple arm (it is behind the head). Tinted lenses must be semi-transparent so the eyes show through; clear frames show the eyes fully. Materials and colours from the items (gold metal, acetate, tinted glass, white plastic, rhinestones), never skin brown.

Make 12 clearly different variants covering: big 1980s oversized square frames, oversized tinted sunglasses (rose, amber, violet, smoke gradient tints), star-shaped sunglasses (gold, hot pink, glitter), gold aviators (gold rim, mirrored or brown gradient lenses), white cat-eye frames (plain, rhinestone-tipped). Painted in front of the character: only glasses pixels, nothing behind the head.

Outputs: artifacts/glasses_01.png .. artifacts/glasses_12.png and artifacts/glasses.json, an array of {"file","name","weight"} with weights summing to 100, rarer items (glitter stars, rhinestone cat-eyes, mirrored aviators) lower.
