아기 폴라로이드 여행 액자 — 가족 여행 추억 카드

[Input]
- output_size: 1024x1024 (1:1 square, frame and feed friendly)
- reference: 1 user-provided photo (family or baby vacation snapshot)

[Purpose]
Compose the user's attached vacation photo into the photo area of a vintage Polaroid frame on top of a flat-lay scene of scattered travel memory props (boarding pass, map, letter, postcard). The result reads as a tangible Polaroid resting on a travel scrapbook, personalized with the destination "{destination}".

[Scene — image-to-image edit, photo preservation]
Use the user's attached photo as the Polaroid photo content itself. PRESERVE the user's photo EXACTLY as is inside the Polaroid window — no style transfer, no face redrawing, no color manipulation beyond a subtle Polaroid warm cast (slightly warm vintage tone overlay only). The photo composition, faces, and subjects must remain unchanged.

Polaroid frame:
- Classic Polaroid Instant frame, white border, photo area approximately 75% of the frame, with a thicker bottom white border for the caption
- Slight torn or worn paper edges, very subtle film grain on the photo content
- Soft drop shadow under the Polaroid suggesting it rests on a surface
- Polaroid slightly tilted 5 to 10 degrees for a casual flat-lay feel

Background flat-lay scene (travel scrapbook tone), scattered loosely around the Polaroid:

1. A vintage international boarding pass with route "ICN → [DEST_CODE auto-derived from destination, see rule below]" where [DEST_CODE auto-derived from destination, see rule below] is automatically derived from the value of {destination}:
   - If {destination} is well-known internationally, use the standard IATA airport code (examples: 제주→CJU, 부산→PUS, 서울→ICN, 오사카→KIX, 도쿄→NRT, 교토→ITM, 후쿠오카→FUK, 발리→DPS, 다낭→DAD, 푸켓→HKT, 방콕→BKK, 세부→CEB, 보라카이→KLO, 싱가포르→SIN, 타이베이→TPE, 하와이→HNL, 파리→CDG, 런던→LHR, 뉴욕→JFK, 로마→FCO, 바르셀로나→BCN)
   - Otherwise use the location name in uppercase English (examples: 제주→JEJU, 오사카→OSAKA, 다낭→DA NANG)
   - NEVER use Korean Hangul characters on the boarding pass — always uppercase English or IATA code
   - Boarding pass also shows illegible sepia filler airline info (no real airline brand names)

2. A small folded paper map showing the {destination} region (city neighborhoods, coastline, or landmark area). Handwritten dots or small circles on 2-3 spots in vintage sepia ink. Map labels written in the LOCAL LANGUAGE appropriate to {destination}:
   - Korean destinations (제주·부산·서울 등) → Korean Hangul labels
   - Japanese destinations (오사카·도쿄·교토 등) → Japanese kanji + hiragana labels
   - Chinese destinations (상하이·베이징·타이베이 등) → simplified or traditional Chinese labels
   - Southeast Asian destinations (발리·다낭·방콕·푸켓·세부 등) → local language labels (e.g. Bahasa for Bali, Vietnamese for Da Nang, Thai for Bangkok/Phuket) OR English labels
   - Western destinations (파리·하와이·뉴욕·런던 등) → English labels (French for Paris is also fine)

3. A partially opened handwritten letter on cream paper (illegible filler handwriting, vintage sepia ink, no specific readable text)

4. A small worn postcard with a faint destination silhouette stamp matching {destination}

5. Tiny scattered accents: a few shells, a pressed flower or dried leaf, a small piece of dried local botanical (e.g. cherry blossom petal for Japan, hibiscus for Hawaii, frangipani for Bali — context-aware to {destination})

Lighting: soft warm daylight from the upper-left, gentle even shadows, scrapbook flat-lay top-down angle.

[Style]
- Photorealistic flat-lay travel scrapbook composition
- Color palette: warm cream paper, soft sepia accents, warm golden vacation palette inside the Polaroid
- Slight film grain across the whole scene, very subtle vignette

[Composition]
- 1:1 square (1024x1024)
- Polaroid occupies the central 55-65% of the frame, slightly tilted 5-10 degrees
- Travel props arranged loosely around the Polaroid, partially overlapping the edges
- Negative space (cream paper) visible between objects, not cluttered
- Top-down flat-lay camera angle

[Text]
- Polaroid bottom white border shows "{destination} 가족 여행" in Nanum Pen Script (soft sepia handwritten Hangul) — caption always in Korean Hangul
- Boarding pass shows uppercase English text only: "ICN → [DEST_CODE auto-derived from destination, see rule below]" plus illegible filler airline info text in sepia print
- Map labels follow the destination's local language as described above
- Postcard, letter, and other props show illegible filler text only (no real readable text)
- No other text anywhere

[🚫 PROHIBITED]
- Real airline brand names on the boarding pass (ANA, Korean Air, JAL, Asiana etc) — generic sepia filler typography only
- Korean Hangul characters on the boarding pass (always uppercase English/IATA)
- Branded characters or IP (Disney, Sanrio etc)
- Heavy retouching of the user's photo inside the Polaroid (must read as the original vacation snapshot)
- Modern anime, manga, 3D, or chibi style
- Real brand logos on letters, maps, or postcards
- Broken or misrendered Hangul on the Polaroid caption
