Final canvas requirement: the delivered project asset must be a 900x1125 transparent PNG. This generation draft is a cropped part source; post-processing will resize the detected part to source alphaBox [488, 307, 586, 349] and paste it at originPercent {'x': 59.67, 'y': 29.16}.
Crop constraint: fill the draft with only this one part, with a small clean margin. Do not draw surrounding face, hair, body, sheet cells, labels, or other avatar parts.
Style/medium: polished anime Live2D PSD part, clean painted edges, matching Vignette avatar renderer style.
Color palette: soft black hair with cool brown highlights, pale warm skin, muted navy school uniform.
Background: perfectly flat solid #00ff00 chroma-key background. Do not use #00ff00 in the part.
Constraints: output one part only, not a character sheet, not multiple variants, no full body unless the part id requires it, no text, no watermark, no shadow, no floor, no frame. Preserve the reference part's transparent silhouette logic and visual scale.
Avoid: collage, sprite sheet, labels, full character, extra facial features, extra parts outside this one part, gradients in the background.
