[Purpose]
Toss-like fintech advertisement poster, designed as a vertical app-promo editorial for social feeds, subway screen ads, and paid mobile placements.
Friendly, clean, MZ-oriented brand visual with a realistic app-screen hero, debit card detail, character illustration, benefit modules, event information, and bold Korean copy hierarchy.

[Composition]
- Main hero area (top 52%): {제품·소재} arranged as the primary focal cluster, with the app screen slightly larger than the card and character to establish a clear visual anchor. Show believable UI details such as account balance cards, spending graph, transfer button, notification pill, and small icon rows.
- Secondary support area (mid-to-lower 28%): add friendly illustration elements, floating rounded badges, tiny receipt snippets, coin icons, and benefit chips placed around the hero so the ad feels like a real fintech campaign rather than a blank product mockup.
- Campaign information area (lower 20%): include short Korean headline/subcopy, CTA button, QR code block, app-store style download buttons, campaign period, small legal disclaimer, and a tiny customer-center line.
- Background treatment: warm white or near-white matte studio surface with gentle depth, subtle paper texture, realistic ambient shadow, faint pastel glow behind the app screen, and a polished social-ad finish.
- Spacing and framing: centered vertical layout with energetic layered placements, readable typography blocks, and a balanced poster rhythm that feels approachable, premium, and content-rich.
- Apply {브랜드 톤}, {시그니처 결}, {카피·타이포}, {레이아웃}, and {비율} as the organizing logic for all placements.

[3. CORE STRUCTURE]
1. Hero cluster: place the app screen front-most, with the card slightly offset behind it and the character illustration adjacent, creating a layered fintech product spotlight. Add tiny UI labels such as “소비”, “송금”, “혜택”, “자산” inside the screen.
2. Copy zone: set a large Korean-first headline near the lower-middle area, supported by two short feature blurbs in pill cards. Example feature blurbs: “이번 달 소비 리포트”, “숨은 혜택 자동 확인”, “1분 만에 송금 완료”.
3. Campaign details: add small but legible poster information such as “2026.05.01–05.31”, “앱에서 바로 확인”, “QR로 혜택 보기”, “광고 코드: TOSS-MAY-247”, and a compact disclaimer line.
4. Accent shapes: add rounded geometric accents in {컬러 팔레트}, including soft circles, capsule tags, small check icons, graph dots, and sticker-like labels. Keep their scale supportive and integrated with the product story.
5. Shadow treatment: give each object a gentle, believable drop shadow that separates it from the matte background while maintaining a light fintech campaign feel.
6. Brand finish: keep the entire scene consistent with {무드·라이팅} and {브랜드 톤}, maintaining a modern fintech ad feel with real promotional context, not a catalog-style product mockup.

[4. STYLE RULES]
- Typography: use Pretendard Bold for the main headline, Pretendard SemiBold for subcopy, and Pretendard Regular for microcopy/disclaimers, with strong sans-serif proportions and large size contrast for ad readability.
- Color palette: use Toss Blue, clean White, and friendly accent tones from {컬러 팔레트}; keep saturation crisp, polished, and premium rather than neon-heavy.
- Border/shadow: soft drop shadow with 4px vertical offset, 14px blur, 14% opacity; use subtle rounded cards, translucent UI panels, and light keyline dividers where useful for a real app-campaign design.
- Typography behavior: set the headline as a strong Korean-first lockup with optional small English support, using compact line breaks and confident spacing. Place microcopy, QR label, and date text smaller but still legible.
- Graphic detail: include believable app icons, spend-category chips, mini charts, notification badges, and small sticker labels such as “NEW”, “혜택”, “무료 송금” to add realism without overwhelming the main message.

[5. VISUAL STYLE]
- Camera / lens: studio product-render look inspired by a 50mm lens perspective at f/5.6, straight-on vertical framing, clean ad composition.
- Lighting: high-key studio lighting with softbox key from upper-left at 45°, very subtle fill from right, faint ambient bounce on the white surface, and a soft blue glow behind the app hero.
- Color grade: cool-clean fintech palette with Toss Blue, white, and soft pastel accent support; keep contrast crisp, edges polished, and UI text sharp.
- Material realism: app screen glass should have a controlled reflection, card should have matte plastic texture with slight edge thickness, and paper-like background texture should be faint but visible.

[6. MOOD]
Premium mobile-finance campaign ad — friendly startup UI aesthetic with a polished Toss-like brand finish, realistic promotional details, smart benefit storytelling, and energetic Korean social-feed readability.

[7. CRITICAL]
- Korean text accuracy: the following strings must appear exactly as rendered text if used in the design: “토스”, “Toss”, “오늘도 돈 관리, 쉽게”, “이번 달 내 소비 리포트”, “혜택 확인하기”, “2026.05.01–05.31”, “QR로 혜택 보기”.
- Maintain a fintech ad composition with an app-screen hero, friendly illustration, large copy hierarchy, QR/download CTA area, campaign date, and small disclaimer line.
- Objects must remain clean, non-distorted, and product-ad polished; avoid any uncanny facial or object deformation.
- Keep the layout centered and vertical, with clear separation between hero objects, benefit cards, CTA, and typography.

[8. 🚫 PROHIBITED]
- Fake official seals / certifications
- Broken Korean characters
