Produce a production-ready transparent PARTS ATLAS for the exact seated character shown in the reference. Redraw the parts, preserving the reference costume, perspective, warm restrained anime painting, slender proportions and thin outlines. This is not a whole character picture. The source frame is design/pose evidence only. Hidden regions must be freshly and coherently painted, not copied from visible cutouts.

WIDE LANDSCAPE image, THREE columns in ONE row. Exactly one disconnected complete part in each column, separated by large fully transparent gutters. Keep every part fully inside its cell with at least 30 pixels of transparent margin on ALL sides. No text, labels, grid, shadows or backdrop. Real alpha transparency. Draw each part large and detailed; their display sizes will be set by the rig, so prioritize pixel detail.

LEFT COLUMN — COMPLETE SLEEVELESS UPPER TORSO. From the bottom of the neck through the seated waist to upper hips. Include the short gray stand collar with its small dark buttons, bare upper chest with thin black horizontal straps, both ivory coat shoulders and folded lapels with muted gold edging, and the central narrow emerald vertically striped bodice. This is one unified clothing-and-torso layer: exactly one collar, two lapels. Match the original open-front design. The chest under the raised hand and forearm must be fully painted with continuous anatomy, straps and green/ivory cloth: imagine that arm is absent. Reconstruct both sleeve attachment areas beneath the shoulders, with sufficient real fabric for rotation. Continue the bodice to the hip with complete stripes. Torso only: NO head, hair, ears, arms, sleeves, hands, badge, lower long coat panels, long hanging green skirt panel or legs. The bottom is a concealed garment attachment with no thick dark cut-line; it must stay safely inside the atlas. Keep the seated three-quarter view and slight lean; do not turn this into a wide frontal vest or close the opening.

CENTER COLUMN — COMPLETE VIEWER-LEFT UPPER SLEEVE. A compact ivory sleeve from a full rounded shoulder cap down to the ONE softly rolled elbow cuff, oriented shoulder upper-right and elbow lower-left, as in the source's raised arm. Include enough actual shoulder fabric to lie under the torso shoulder throughout the bend. Precisely one rolled cuff, soft folds, pale gray shading. No body skin, forearm, glove, badge, torso, duplicate cuff or floating ornaments. The cuff opening is part of the sleeve design; no cast shadow outside the cloth. Do not chop off its shoulder cap.

RIGHT COLUMN — COMPLETE VIEWER-RIGHT UPPER SLEEVE. Narrower due to perspective, shoulder upper-left to elbow lower-right. Ivory sleeve ending in the original broad pale green diamond-patterned cuff with muted gold border. Exactly one cuff, structurally connected to the sleeve. Fully painted hidden shoulder cap. No skin, forearm, hand, bow, torso or badge. All sleeve edges and lower cuff fully visible within the cell.

Completeness matters more than a deceptive assembled preview. Do not include an assembled character. Parts may overlap only after rigging, never on this sheet. Preserve original material identity and newly paint hidden surfaces; never stretch edge colors to fabricate them.
