[Purpose]
Public recruitment poster for a city hall / district office lifelong learning course program, A4 vertical layout for community noticeboards, municipal website banners, and mobile sharing.
Friendly civic-service poster with clear enrollment messaging, realistic class photography, and practical course information that residents can read quickly.

[Composition]
- Main poster follows a vertical civic announcement layout for {비율}: a civic header and recruitment badge at the top, a warm hero image in the upper section, a large headline below, then course schedule, fee, venue, application, and contact details arranged as readable information cards.
- Place {주최기관} and {강좌명} near the top as the organizational/course identifier, aligned like a municipal lifelong-learning announcement rather than a commercial ad.
- Add a small issue-style civic label such as “2026 상반기 평생학습 프로그램” and a rounded badge reading “선착순 접수” beside the header.
- Use {헤드라인} as the primary attention line, large and friendly, followed by {서브카피} in a smaller supportive line.
- Insert {hero이미지} as the central visual focus: real classroom atmosphere with learners, instructor gestures, notebooks, tablets, craft tools, cooking utensils, language flashcards, or calligraphy brushes depending on the course theme.
- Build the lower section with {모집기간}, {운영기간}, {수강안내}, {신청방법}, {장소}, and {문의} as compact information rows with icons, dividers, and colored labels.
- Add a footer sponsor/administration strip with {주관협력}, {웹주소}, a small QR-code placeholder, and a public-service notice line.
- Apply {컬러팔레트} across the entire design with civic blue-green accents, white paper texture, charcoal text, soft panels, and friendly decorative graphics such as learning-themed doodle icons, calendar dots, and small page-corner stickers.

[3. CORE STRUCTURE]
1. Top header area (upper 12%): Place {주최기관} as a civic label with the main title “시민 강좌 모집”; add {강좌명}, “2026 상반기”, and a small badge “접수중 · 선착순”.
2. Hero image block (upper 36%): Show {hero이미지} as a realistic municipal brochure photograph with warm classroom depth, visible learning materials, diverse adult learners, and an instructor helping participants.
3. Headline block (mid 13%): Set {헤드라인} in the largest Korean type, with {서브카피} underneath; add a small decorative underline or blue-green ribbon shape.
4. Event details block (mid-lower 18%): Present {모집기간}, {운영기간}, {수강안내}, and {참가비} in four labeled cards using calendar, clock, certificate, and won-symbol icons.
5. Application block (lower 13%): Present {신청방법}, {장소}, and {문의} with clear emphasis on application dates, venue, phone number, and online route.
6. Footer / sponsor area (bottom 8%): Include {주관협력}, {웹주소}, QR-code placeholder, “자세한 내용은 홈페이지 공지사항을 확인하세요”, and small decorative graphics from {장식요소}.

[4. STYLE RULES]
- Typography: Pretendard and Noto Sans KR, bold 700–800 for the headline, medium 500–600 for supporting details, size hierarchy with the headline roughly 2.5–3x larger than body text.
- Color palette: {컬러팔레트} with civic blue, muted green, clean white, warm off-white paper, and charcoal black; use pale tinted panels for information grouping.
- Graphic treatment: soft rounded rectangles, 1px blue-gray divider lines, gentle card shadows around 4px y-offset, 10px blur, 12% opacity, small line icons for date/time/place/phone, and learning-themed decorative stickers.
- Information design: dates and deadlines must be visually highlighted with accent color; phone and website should be placed in the footer where residents can easily find them.
- Poster realism: include small print details such as QR code placeholder, “수강료 감면 대상 별도 문의”, “정원 초과 시 조기 마감”, and a municipal noticeboard-friendly print texture.

[5. VISUAL STYLE]
- Camera / lens: documentary poster photo feel, Canon EOS R5 with RF 35mm f/1.8 at f/5.6 for a balanced classroom scene, or Canon EOS R6 Mark II with RF 50mm f/1.8 for a friendly enrollment brochure look.
- Lighting: soft diffused daylight from upper-left, with gentle fill from front-right; keep the scene bright, warm, and believable like a municipal lifelong-learning center brochure shot.
- Color grade: crisp civic blue + fresh green + neutral white balance, slightly softened contrast, clean public-service print finish with natural skin tones and readable text overlays.

[6. MOOD]
Friendly public-service announcement — trustworthy, welcoming, and useful, like a well-designed municipal brochure posted at a community center, library, subway noticeboard, and city hall website.

[7. CRITICAL]
- Korean text accuracy: 반드시 아래 문구가 정확히 보여야 함
  - "올해는 새로운 걸 배워볼까요?"
  - "시민 강좌 모집"
  - "모집기간 2026.04.01–04.15"
  - "매주 1회 90분 · 8주 과정"
- Render all key Korean poster text cleanly and legibly: {주최기관}, {강좌명}, {모집기간}, {운영기간}, {수강안내}, {참가비}, {신청방법}, {장소}, {문의}, {웹주소}.
- Layout invariants: vertical A4-style poster, civic header at top, hero classroom image above the headline, details stacked in the lower half, footer with sponsor area and QR-code placeholder.
- People in the hero image must look natural, adult, friendly, and appropriate for a public lifelong-learning class.

[8. 🚫 PROHIBITED]
- Fake official seals / certifications
- Broken Korean characters
- Celebrity composites or recognizable public figures
- Face or body distortion in any people shown
