Pastel Number Balloon Family Portrait

[Input]
- output_size: 1024x768 (4:3 landscape)
- reference: 1 family/sibling photo (1-3 babies or kids)
- user_text_number: {user_text_number}

[Purpose]
Convert the user's attached family/sibling photo into a soft pastel number balloon anniversary portrait. The number "{user_text_number}" is spelled out by large soft pastel foil balloons, with the children sitting/standing in front.

[Scene — image-to-image edit, preserve identities]
Use the attached photo as the base. PRESERVE the identity of each person in the photo (face proportions, age, hair, skin tone) and their relative positions. Re-render them in the same poses but in a clean studio scene.

Number balloons:
- Large soft pastel matte foil balloons spelling out "{user_text_number}" — placed BEHIND or BESIDE the children, taking up the upper portion of the frame
- SOFT pastel finish (matte, not glossy) — cream, dusty rose, pastel mint, soft lavender, peach (mix and match across the digits)
- Rounded soft shapes, NOT sharp metallic foil — gentle curvy edges
- Each digit a slightly different pastel color

Children:
- Sitting on a clean ivory wood floor or standing in front of the balloons
- Wearing soft pastel outfits — if the photo shows specific outfit (e.g., strawberry print), preserve the print but soften saturation
- Natural happy expressions, candid feel

Background: clean off-white seamless backdrop, warm soft light

[Style]
- Premium Korean studio anniversary photography
- Soft warm daylight, gentle golden hour mood
- Low saturation, dreamy pastel tone
- Clean and minimal

[Composition]
- 4:3 landscape
- Number balloons span the upper 50-60% of frame
- Children sit/stand in the lower 50-60%, naturally arranged
- Plenty of breathing room

[Text]
- Use the exact number provided: "{user_text_number}"
- The number is FORMED BY balloons (not overlay text)
- No other text anywhere

[CRITICAL — Preserve identities]
- Each face must clearly match the corresponding person in the attached photo
- Relative positions of the children preserved (do not swap places)
- Age and hair style preserved

[🚫 PROHIBITED]
- Sharp, glossy, metallic foil balloons (must be soft matte pastel)
- Saturated, neon, or harsh colors
- Cluttered scene (must stay minimal)
- Brand logos, character merchandise
- Overlay text (number must be balloon-shaped)
