어린이 증명사진 — 어린이집 유치원 입소용 ID 포트레이트

[Input]
- output_size: 1024x1024 (1:1 square, ID portrait framing)
- reference: 1 Korean child's photo (front-facing, clear face recommended)

[Purpose]
Convert the user's attached child photo into a clean studio-style ID portrait suitable for daycare, preschool, academy registration, or passport drafts. The child appears from chest up against a soft solid backdrop with a subtle vignette in classic Korean kindergarten ID photo composition.

[Scene — image-to-image edit, preserve identity]
Use the user's attached photo as the base. PRESERVE the child's identity (face proportions, eye shape, age, hair style, skin tone) and redraw as a clean photorealistic ID portrait. The child must remain recognizably the same.

Child wears a crisp white oxford dress shirt with a clean pointed collar, neatly pressed, no patterns, no logos. Hair: {hair_description}.

Pose: chest-up framing with the head fully visible, approximately 10% empty headroom above the hair, shoulders visible at the bottom edge. Straight-on frontal angle, eye-level camera. Soft neutral expression with a very gentle smile, eyes looking directly at the camera.

Setting: solid {background_color_description} studio backdrop with a subtle soft vignette (slightly darker toward the corners, classic studio look). No props, no objects, no patterns in the background.

Lighting: soft flattering studio lighting, frontal key light with mild fill, gentle catchlights in the eyes. No harsh shadows on the face or backdrop.
