[Purpose]
도서관 낭독회·작가 사인회 안내 포스터, {비율} 기반의 A4 세로형 이벤트 홍보물, 도서관/서점 현장 게시와 SNS 공유용.
책 정물, 작가 실루엣, 서가 배경을 활용한 문학 행사 포스터 느낌으로, 행사명·일시·장소·신청 정보를 한눈에 전달하는 편집형 레이아웃.

[Composition]
- Poster is a vertical A4 layout with a strong top-to-bottom reading flow; title block occupies the top 18%, hero illustration/photo area takes about 38–42%, and event details, ticket/application info, sponsor strip fill the lower section.
- Main subject stays slightly above center; {hero 이미지} is framed as the central visual anchor with warm paper texture, library shelf depth, reading lamp glow, bookmark, pencil note, open book pages, and small decorative literary motifs.
- Background treatment: warm library interior tone with subtle paper grain, ivory base, soft shelf texture, visible book spines, a table edge, gentle shadows, and print-friendly matte finish.
- Use {행사번호}, {포스터 카피}, {행사 종류}, {초청 작가·작품}, {일시}, {장소}, {진행 시간}, {참여 방법}, {참가비}, {신청 링크 문구}, {문의처}, {주최·후원}, {티켓 안내}, {hero 이미지}, {장식 모티프}, {컬러 팔레트}, {비율} as editable content anchors.
- Lower third contains a realistic event information panel: date/time/venue line, participation method, ticket or reservation note, inquiry contact, and a sponsor/organizer area separated by thin editorial rules.

[3. CORE STRUCTURE]
1. Top header band: place {행사번호} as a small catalog-like label near the top edge, then set {행사 종류} as the primary headline, large and bold, with {포스터 카피} as a short sub-copy below it; add a thin separator rule and small decorative book/page marks.
2. Hero zone: show {hero 이미지} as the visual focal point, either a warm book still life, a soft author silhouette near shelves, or a quiet library desk scene; include tactile details such as page texture, bookmark ribbon, pencil annotation, reading glasses, library checkout card, and warm shelf lighting.
3. Event title block: place {초청 작가·작품} directly below or overlapping the lower edge of the hero zone in stacked lines for author name and book title; use a refined editorial emphasis so it reads as the featured program.
4. Information block: arrange {일시}, {장소}, {진행 시간} in a clearly divided section with date/time emphasized; use small pictogram-style labels such as DATE, PLACE, TIME rendered as simple typographic tags.
5. Participation / ticket block: place {참여 방법}, {참가비}, {티켓 안내}, and {신청 링크 문구} in a practical lower-panel layout; include a small QR-style application box, reservation number tab, or perforated ticket-like shape to make the poster feel real.
6. Footer area: add {주최·후원} and {문의처} as a sponsor/organizer strip with small logo placeholders, library branch line, contact phone/email text, and page-like divider decoration using {장식 모티프}.

[4. STYLE RULES]
- Typography: Pretendard or Noto Sans KR for the main body, weight 700–800 for headlines, 400–500 for details; title 42–58 px, program title 30–42 px, details 18–24 px, footer 13–16 px; use comfortable line spacing for Korean readability.
- Color palette: use {컬러 팔레트} with ivory #F5F0E6 as base, warm brown #8A6446, indigo #2F3E5C, charcoal #2B2B2B, and a muted burgundy accent for ticket tags or bookmarks.
- Editorial decoration: thin charcoal rules, book-page dividers, small quotation marks, bookmark ribbon, date stamp texture, library checkout-card grid, and a modest sponsor strip at the bottom.
- Border/shadow: thin charcoal rules, soft drop shadow 4px y-offset, 12px blur, 15% opacity; matte poster print feel with natural paper grain and realistic ink density.
- Ratio/layout: keep the whole design optimized for {비율}, preserving generous margins, clear vertical hierarchy, and enough safe area so no essential text is cropped.

[5. VISUAL STYLE]
- Camera / lens: editorial still-life look shot on a full-frame camera with 50mm lens at f/4 for balanced depth and clean product-style framing; if using a library interior feel, emulate a 35mm documentary composition.
- Lighting: soft window light from upper-left at about 45°, with a faint fill from the right to keep book edges and silhouette contours readable; warm practical lamp glow may appear near the hero desk area.
- Color grade: warm cream + brown + muted indigo + charcoal, with slightly desaturated shadows, paper-like highlights, realistic printed ink texture, and a calm cultural-event poster finish.

[6. MOOD]
Premium literary event editorial — think Kinfolk magazine spread meets a quiet Korean public library poster, with a warm, trustworthy, well-organized cultural-announcement tone.

[7. CRITICAL]
- Korean text accuracy: 반드시 정확히 들어가야 하는 문구:
  - {행사번호}
  - {포스터 카피}
  - {행사 종류}
  - {초청 작가·작품}
  - {일시}
  - {장소}
  - {진행 시간}
  - {참여 방법}
  - {참가비}
  - {티켓 안내}
  - {신청 링크 문구}
  - {주최·후원}
  - {문의처}
  - {비율}
- 포스터 하단에는 실제 행사물처럼 “신청”, “문의”, “주최/후원” 정보가 구분되어 보여야 하며, QR-style 박스나 티켓 탭은 장식이 아니라 신청 안내 요소처럼 배치한다.
- All Hangul characters must render cleanly with no broken syllables, no substitution glyphs, and no accidental English replacements in the Korean text zones.
- Keep the composition poster-like and readable, with all event information legible at A4 viewing distance.

[8. 🚫 PROHIBITED]
- Fake official seals / certifications
- Broken Korean characters
- Celebrity composites or misleading real-person likeness
- Illegible event details caused by text distortion
