Four full-body versions of the same character side by side at identical scale and pose, standing on one baseline: forest ranger (moss-green hooded cloak, leather armor, bow on the back), winter expedition (white fur-lined parka, snow goggles, ice axe), royal ceremonial (cobalt and gold tabard, silver circlet, long cape), battle-worn veteran (scratched steel pauldrons, torn cloak, bandaged forearm). Orthographic front view, neutral light-grey studio background, soft even lighting, consistent face, hair and body proportions across all four. Stylized hand-painted 3D game art, clean silhouettes, production design sheet. No text, no letters, no numbers, no labels, no logos, no watermark, no UI.","aspectRatio":"1:1","idempotencyKey":"a-new-uuid-per-run"}'
