아기 개인화 9컷 콜라주 (이름·날짜)

[Input]
- output_size: 1024x1024 (1:1 square)
- reference: 1 baby photo (front-facing, shoulders visible)
- user_text_name: {user_text_name}
- user_text_date: {user_text_date}

[Purpose]
Create a personalized 3×3 expression collage of the baby — 9 varied portrait shots laid out in a grid, with the baby's name (English) and date composited to the right side as the design accent.

[Scene — image-to-image edit, preserve baby identity]
Use the attached photo as the base baby. PRESERVE the baby's identity (face proportions, age, hair style, skin tone) across all 9 panels. Re-render the baby in 9 DIFFERENT expressions and small variations:
1. Big smile, looking at camera
2. Cute pucker / kiss face
3. Eyes closed, peaceful laugh
4. Wearing tiny sunglasses, cool pose
5. Surprised / "oh!" expression
6. Hand on cheek, shy expression
7. Wearing a small flower crown, gentle smile
8. Side glance, mischievous smile
9. Hands cupping cheeks, "so cute" pose

Outfit: simple ivory or pastel onesie/dress consistent across all 9 panels.

Layout: clean 3×3 grid taking up the LEFT 70-75% of canvas. Each cell separated by thin white gutter. {background_color} is the dominant card background (visible around the grid and behind the text).

Right 25-30% of canvas:
- Large vertical-oriented English name "{user_text_name}" — hand-drawn outlined letter style, slightly textured (NOT a clean digital font, more like sketched outline), in a slightly darker tone of the background color
- Below the name (or bottom-right): the date "{user_text_date}" in small, neat sans-serif

[Style]
- Premium Korean studio collage aesthetic (Insta-friendly)
- Soft, slightly warm tones
- Clean grid lines, generous white gutters
- Hand-drawn outlined name treatment (like a personal sketch)

[Composition]
- 1:1 square
- 3×3 grid on the left 70-75%
- Vertical name + date on the right 25-30%

[CRITICAL — Preserve baby identity]
- Face proportions, age, hair, and skin tone must be consistent across ALL 9 cells and match the attached photo
- Only expression and small props (sunglasses, flower crown) vary between cells

[Text]
- Use the exact English text provided: "{user_text_name}" and "{user_text_date}"
- English letters in the name only — large hand-drawn outlined letters
- Date in clean small sans-serif
- No other text anywhere

[🚫 PROHIBITED]
- Cluttered or inconsistent baby identity between cells
- Photorealistic harsh details — keep soft and warm
- Brand logos
- Korean characters in the name (English letters only — that's the design intent)
- Decorative emojis or stickers on the photos
