Pregnancy Week-by-Week Card

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

[Purpose]
Convert the user's attached pregnancy photo into a Korean week-by-week pregnancy card. Wrap the user's photo with a designed card overlay (header, week badge, baby's nickname, developmental info). Used by expecting mothers as Instagram posts or pregnancy journal pages.

[Scene — image-to-image edit, preserve user's photo]
Use the attached photo as the base. PRESERVE the original mother's face, body shape, posture, and expression — do not generate a different person. The photo of the mother is the HERO visual element of the card.

Layout the card AROUND the preserved photo:
- Top strip (~8%): a small decorative header band with "{header_title}" in subtle Korean serif, centered. Add a small decorative leaf or sparkle motif.
- Hero photo area (middle 50-55%): the user's original photo, lightly retouched (soft brightening, gentle skin smoothing, slight warm color grading — "뽀샤시" effect) but NOT altered in identity. Frame it with a soft rounded rectangle or polaroid-style border in {mood_color}.
- Hero text overlay (corner of the photo or just below): a LARGE bold "{week_number}주" (week number + Korean character 주), and the baby's nickname "{taemyung} ❤" in a warm handwritten Korean script. Both elements sit elegantly on or near the photo edge.
- Info section (below photo, ~25%):
  - Small subheader "👶 우리 {taemyung}" followed by 3 short bullets (each starting with "•") describing typical fetal development at {week_number} weeks of pregnancy — generate these based on standard week-by-week pregnancy guidance.
  - Small subheader "🤰 엄마의 변화" followed by 2-3 short bullets (each starting with "•") describing typical maternal body changes at {week_number} weeks.
- Optional personal note line: if a personal message is provided, render it as a small warm handwritten Korean line just above the footer: "{personal_message}". If not provided, skip this line entirely.
- Footer decorative band (~5%): a single small line — "오늘의 {taemyung}, {week_number}주차" — in warm small Korean script, centered. Subtle decorative dots or sparkles on either side.
- Background of the entire card: {mood_color} soft pastel tone with gentle texture. The photo sits inside this color-themed page.

[Photo Retouching — light, identity-preserving]
Apply ONLY the following gentle adjustments to the user's photo:
- Soft brightening of skin tones ("뽀샤시" Korean photo style — gentle, natural)
- Slight warm color grading to match the {mood_color} tone
- Small soft glow around the silhouette
Do NOT alter facial features, body shape, age, or ethnicity. Keep the mother fully recognizable.

[Style Rules]
- Typography: Pretendard ExtraBold for "{week_number}주" (large hero), Cafe24 Ohsquare or warm Korean handwritten script for "{taemyung} ❤" (warm, personal feel), Pretendard Bold for subheaders, Pretendard Regular for bullet body text. All bullets use "•" character.
- Color palette: {mood_color} as dominant card frame and background. Dark warm gray text. The photo retains its natural colors with only the light retouching above.
- Decorative motifs: tiny sparkles, soft leaves, small hearts at corners — outline only, subtle accent color.
- Layout: feels like a beautiful page in a pregnancy journal, not a clinical info card. Airy, warm, personal.

[Visual Style]
- The photo is photographic (real), the card frame around it is flat 2D editorial vector.
- Card frame: soft pastel, no shadows except a very subtle photo border drop-shadow.
- Pure flat colors for the card design; the photo keeps its natural photographic quality.

[CRITICAL — Korean text accuracy]
Render ALL Hangul correctly, character by character, with NO broken or misrendered jamo. The exact strings to render:
  - Header: "{header_title}"
  - Hero: "{week_number}주", "{taemyung} ❤"
  - Subheaders: "👶 우리 {taemyung}", "🤰 엄마의 변화"
  - Baby development bullets: 3 short bullet lines (model-generated based on {week_number}), each starting with "•"
  - Mom change bullets: 2-3 short bullet lines (model-generated based on {week_number}), each starting with "•"
  - Optional personal note: "{personal_message}" (only if provided)
  - Footer: "오늘의 {taemyung}, {week_number}주차"
Double-check every Hangul syllable. Each bullet must start with the "•" character.

[CRITICAL — Photo identity preservation]
- The mother in the final card MUST be the same person as in the attached photo (face, body, hair, expression preserved).
- Light retouching (brightness, warmth, glow) is OK, but NO facial restructuring, body alteration, age change, or ethnicity change.
- If the photo shows the belly, keep the belly shape visible and unchanged.

[🚫 PROHIBITED]
- Generating a new/different person (must preserve the attached mother)
- Ultrasound images, sonogram visuals, real or fake fetal imagery
- Heavy retouching that changes identity (filler, beautification beyond natural)
- Broken or misrendered Hangul characters
- Medical clinical imagery, anatomical fetal detail
- 3D, anime, manga style for the photo
- Real brand logos or celebrity overlays
