아이 생일 포스터

[Input]
- language: Korean + English
- output_size: 1024x1536 (2:3 portrait)

[Purpose]
Convert the attached kid's photo into a 'HAPPY Birthday' celebration poster. Background-remove the child, place on a clean cream backdrop, and add a designed birthday header + footer. The card is reused every year by changing the ordinal age.

[Scene — image-to-image edit, background removal + design wrap]
Use the attached photo as the base. REMOVE the original background completely. Keep ONLY the child (face, hair, outfit, pose, hands — everything that is the child themselves). Place the child on a clean {mood_background} backdrop, slightly larger than the photo subject (the child fills about 55-65% of the card height).

Apply light retouching:
- Soft brightening of skin tones ("뽀샤시" Korean photo style)
- Slight warm color grading
- Gentle skin smoothing
- Do NOT alter facial features, body, age, ethnicity, or outfit

[Card Layout]
- Top 25%: header text area centered:
  - A small ordinal pill (rounded oval outline) containing "{birthday_age_ordinal}" in small clean sans-serif at the top
  - Below the pill, large bold uppercase sans-serif "HAPPY"
  - Below that, large flowing cursive script "Birthday" (overlapping slightly with HAPPY for elegance)
  - Below that, smaller sans-serif "to you"
- Middle 55-60%: the cut-out child (background removed) placed centered, with the {mood_background} backdrop showing through.
- Decorative motifs (scattered around the child, not overlapping the face): hand-drawn outline {decorative_motifs} — keep small, 6-10 elements total, not too busy.
- Bottom 12-15%: a small ribbon banner with single line text: "{birthday_date} {baby_name}의 생일" in small clean sans-serif Korean.

[Style Rules]
- Typography:
  - "HAPPY": large bold uppercase sans-serif (Pretendard ExtraBold or similar)
  - "Birthday": large flowing English script font (cursive, elegant)
  - "to you": medium sans-serif
  - Ordinal pill text: small clean sans-serif
  - Korean footer line: clean Pretendard Medium
- Color palette: {mood_background} backdrop, {accent_color} for header text and decorative motifs.
- Decorative motifs: hand-drawn outline style (rough sketch feel) in {accent_color} — hearts, sparkles, small stars, doodle lines.
- Layout: poster-feel, airy, Canva-template aesthetic. The child is the visual hero.

[Visual Style]
- The child is photographic (real photo, background removed).
- The header text and decorations are clean editorial vector style.
- Soft cream/pastel background, no harsh shadows.
- 2:3 portrait poster output (1024x1536).

[CRITICAL — Korean text accuracy]
Render all visible text correctly:
  - Ordinal: "{birthday_age_ordinal}" (e.g., 1st, 2nd, 3rd, 4th, 5th, 10th, 18th)
  - Header: "HAPPY Birthday to you"
  - Footer: "{birthday_date} {baby_name}의 생일"
Double-check every Hangul syllable in the footer.

[CRITICAL — Background removal + identity preservation]
- The original background MUST be completely removed.
- The child's face, body, outfit, hair, and pose MUST be preserved from the attached photo.
- Place the child on the new {mood_background} backdrop seamlessly (clean edges, no halo, no artifacts).
- Decorative motifs sit on the backdrop, NEVER on the child's face or body.

[🚫 PROHIBITED]
- Keeping the original background
- Replacing the child with a different person
- Heavy retouching or beautification
- Broken Hangul in the footer
- Real brand logos or celebrity overlays
- 3D, anime, manga style
- Decorative motifs covering the child's face
