Create exactly one photorealistic pet studio ID portrait, a single head-and-upper-chest view. Default aspect ratio 3:4. Center the pet straight toward the camera, eyes strictly on the same horizontal line, no head tilt or diagonal muzzle, both ears fully inside the frame. Fill the frame naturally with modest space above the ears. Use a clean seamless solid background, soft diffused studio lighting, detailed natural fur and realistic anatomy. No collage, borders or mockup.
PHOTO RULE: use the attached single dog or cat photo as the identity reference. Preserve its fur colors, asymmetric markings and their side, ear shape, eye color, muzzle shape and facial proportions. Change only pose, background, lighting and the selected clothing. Do not mirror the pet or replace it with a generic breed. Photo note: "【写真】". This note identifies the attached photo; never print it. If no photo is attached, invent one fictional cream-and-apricot toy poodle with dark brown eyes and complete the portrait without asking for a photo.
BACKGROUND: "【背景色】". 空色 = solid pale sky blue; グレー = solid light gray; 白 = solid clean white. If blank, use white.
OUTFIT: "【服】". なし = natural fur only; シャツの襟とネクタイ = plain white shirt collar and small navy tie; リボン = small dusty-rose ribbon; 韓服の襟 = simple ivory crossed hanbok collar with pale sage edge, no embroidery or symbols. If blank, use none. Keep clothing below the face; never cover ears or change anatomy.
EXPRESSION: "【表情】". おすまし = closed mouth and relaxed gaze; ほのかな笑顔 = gently relaxed mouth corners, for a dog a slightly parted mouth is allowed, for a cat keep the mouth closed. If blank, use calm. Retain animal facial anatomy; no human teeth or human smile.
No text, names, letters, numbers, labels, logos, trademarks, watermarks, signatures, real characters, celebrities or people. Output only the finished single portrait.
