提示詞原文

[Input]
- language: Korean
- output_size: {비율/사이즈}

[Purpose]
Korean brand message campaign poster for social, OOH, and print use.
Large-format vertical ad with a bold headline, cinematic key visual, campaign metadata, venue/date information, sponsor strip, QR-style participation block, and premium editorial brand presence.

[Composition]
- Main subject occupies about 62% of the frame, either as a large realistic photo of a running Korean 20s person or a single dominant message block, depending on {키 비주얼}.
- Build a strict premium poster hierarchy with cinematic image depth, bold message placement, tactile paper texture, accent graphic lines, and readable campaign information.
- Place {브랜드명} as a compact brand lockup in the upper-right corner or as a single-line footer, using {브랜드 로고 위치}.
- Set {캠페인 메시지} as the main statement and {부제 카피} as the secondary line, both readable at a distance.
- Add realistic poster details: {캠페인 일자}, {캠페인 시간}, {캠페인 장소}, {참여 안내}, {캠페인 코드}, sponsor area, and a small QR-style participation box.
- Use the exact visual tone described in {컨셉 톤}, with a monochrome base and one sharp accent color.
- 전체 포스터는 {비율/사이즈}에 맞춰 여백, 타이포그래피 크기, 정보 블록 비례가 안정적으로 보이도록 구성한다.

[3. CORE STRUCTURE]
1. Hero zone (center 60%): Build the composition around {키 비주얼} as the dominant visual, with cinematic contrast, crisp subject separation, motion energy, and a believable urban running atmosphere.
2. Message zone (upper third or center-left): Render {캠페인 메시지} in a bold sans-serif headline, oversized and highly legible, so it becomes the primary campaign statement.
3. Sub-copy zone (beneath headline or near hero edge): Place {부제 카피} in smaller text with tight tracking, functioning as a refined supporting campaign line.
4. Campaign detail zone (lower third): Add a structured information block containing {캠페인 일자}, {캠페인 시간}, {캠페인 장소}, and {참여 안내}; use thin dividers, small labels, and a practical poster information rhythm.
5. Brand zone (top-right or bottom line): Place {브랜드명} according to {브랜드 로고 위치}, styled like a premium campaign signature with a compact wordmark treatment.
6. Sponsor and CTA zone (bottom strip): Include {후원 문구}, a small QR-style square labeled {QR 라벨}, and the campaign code {캠페인 코드}; make it feel like an actual street poster or launch campaign print.
7. Graphic system: Apply {컨셉 톤} across the full poster, using monochrome blacks, whites, and grays plus a single accent color for arrows, route lines, date markers, underlines, or small geometric graphics.
8. Print-readability pass: Maintain strong contrast, sharp typographic hierarchy, and clear separation between headline, image, details, sponsors, and participation CTA for Instagram feed, OOH, and A1/A0 print.

[4. STYLE RULES]
- Typography: Use Pretendard ExtraBold or Inter Tight Black for the main headline, Noto Sans KR SemiBold for Korean supporting copy, and a clean condensed sans-serif for metadata; headline size should feel 88–120 px equivalent, subtitle 28–38 px equivalent, metadata 18–26 px equivalent.
- Color palette: Follow {컨셉 톤} with black #0B0B0B, charcoal #2A2A2A, off-white #F5F5F2, and one accent color matching the brand signature.
- Graphic details: Add accent route lines, small coordinate marks, subtle halftone grain, poster-fold texture, thin dividers, and a QR-style participation box that supports the campaign concept.
- Text layout: Combine large Korean headline blocks with compact metadata rows; align details precisely so the poster feels designed for a real brand launch.
- Shadow and contrast: Use a subtle soft drop shadow only if needed for headline separation, about 4px y-offset, 14px blur, 12% opacity.

[5. VISUAL STYLE]
- Camera / lens: Realistic editorial sports portrait photographed on a 85mm f/1.8 lens or 70–200mm at 135mm, shallow depth of field, clean subject isolation, magazine-ad sharpness.
- Lighting: Cinematic directional light from upper-left with a controlled rim light from the right, as if shot during blue hour or in a studio with a hard key + soft fill.
- Color grade: High-contrast monochrome with one accent color preserved at full saturation; deep blacks, cool grays, and crisp highlight roll-off.
- Surface realism: Printed campaign poster feel with slight paper grain, ink density variation, very subtle scuffing near edges, and realistic overlay of typography on the photographic key visual.

[6. MOOD]
Premium global brand campaign editorial with cinematic sports-commercial energy, confident Korean copywriting, urban night-running atmosphere, and polished launch-poster realism.

[7. CRITICAL]
- Korean text accuracy: 반드시 아래 문구를 정확히 렌더링할 것.
  - {브랜드명}
  - {캠페인 메시지}
  - {부제 카피}
  - {캠페인 일자}
  - {캠페인 시간}
  - {캠페인 장소}
  - {참여 안내}
  - {후원 문구}
  - {QR 라벨}
  - {캠페인 코드}
- Poster size and ratio: {비율/사이즈}를 기준으로 최종 포스터의 세로형 광고 비례와 출력용 안정감을 유지할 것.
- Layout must feel like a major brand campaign poster: bold, premium, information-rich, realistic as a printed campaign asset, and highly legible at a distance.
- If the hero includes a person, the running pose must be anatomically correct and natural.
- All Korean typography must be clean, readable, and free of distorted syllables.

- Fake official seals / certifications
- Broken Korean characters
- Celebrity composites or unauthorized celebrity likenesses
