[Purpose]
Korean event poster for a concert or festival, vertical 9:16 format, designed for social media promotion, street posting, ticket booth signage, and venue entrance publicity.
Bold typography-first poster with a vivid graphic + photo hybrid feel, built to read instantly at thumbnail size while still containing realistic event-poster details such as schedule, ticket note, sponsor strip, and venue guidance.

[Composition]
- Center composition: {이벤트 이름} dominates the middle 50% of the frame as the main hero typography, with strong visual weight, tight vertical stacking, and a slight neon-lit dimensional treatment.
- Subheader placement: {부제} sits directly below the main title in smaller Korean type, aligned to the same center axis with confident spacing and a clear festival-tagline feel.
- Top area: {이벤트 종류} appears as a small category label near the upper margin, paired with compact poster metadata such as "SEOUL SUMMER NIGHTS", "VOL.07", and "LIVE FESTIVAL POSTER".
- Bottom footer: {날짜}, {장소}, and {라인업} are grouped in a structured footer band across the lower 18–22% of the poster, with date/time, venue, lineup strip, ticket info, and small contact details.
- Background treatment: a night festival atmosphere with layered city lights, dark sky gradients, stage beams, LED screen glow, faint confetti, silhouetted crowd hands, speaker stacks, and performance haze, using diagonal or horizontal division to create motion.
- Framing direction: keep the title unobstructed; background visuals, decorative light trails, and crowd silhouettes should frame and energize the typography without covering the letterforms.
- Add realistic event-poster elements: small sponsor area near the lower edge, QR-code-like ticket block, admission note, venue direction line, and tiny production credits.

[3. CORE STRUCTURE]
1. Background layer — Build a deep night backdrop with a gradient from indigo to near-black, then add blurred Seoul urban light clusters, stage glow, smoke haze, lens bokeh, LED particles, and faint reflections like a real outdoor music festival poster.
2. Mood visual layer — Place a diagonal or broad horizontal visual field of night-sky, city nightscape, silhouetted crowd, raised hands, stage truss, and moving spotlights behind the title, with strong contrast separation for legibility.
3. Title layer — Set {이벤트 이름} in very large, bold display type centered in the frame, occupying about half of the poster height, with sharp edges, high contrast, subtle magenta/cyan glow, and a tactile printed-poster presence.
4. Subtitle layer — Place {부제} beneath the main title in smaller Korean typography, slightly lighter weight, with comfortable line spacing and a clean centered rhythm; include a tiny divider line or dot markers around the subtitle if it supports the design.
5. Event info layer — Add {날짜} and {장소} in the footer area using compact but readable type, aligned left-to-right or stacked in a neat block; also render supporting Korean event details such as "입장 16:00", "공연 18:30", "우천 시 정상 진행", and "예매처 안내".
6. Lineup layer — Render {라인업} as a secondary information row in the footer, using smaller tracking and clear separators so it reads like a lineup strip; add label text such as "LINE UP" and separate artists with bullets, slashes, or vertical bars.
7. Category label — Position {이벤트 종류} near the top as a small descriptor, accompanied by a thin rule, issue-like metadata, and a short English event label such as "SEOUL SUMMER NIGHTS".
8. Ticket and sponsor layer — Add a realistic lower-corner ticket block with "TICKET OPEN", "1일권 ₩88,000", "양일권 ₩149,000", a small QR-like square pattern, and a sponsor/partner row reading "주최 서울라이브랩 · 후원 문화도시서울 · 문의 02-0000-2026".
9. Decorative graphic layer — Add neon line arcs, small starbursts, waveform bars, equalizer blocks, thin grid marks, tiny arrows, and magenta/cyan light leaks to make the poster feel printed, promotional, and content-rich.

[4. STYLE RULES]
- Typography: use Pretendard ExtraBold or Noto Sans KR Black for the main title, Pretendard Medium for supporting Korean text, and a condensed sans for footer details; main title size should feel oversized and poster-defining.
- Color palette: use deep navy #0B1020, indigo #1A2458, neon cyan #39D5FF, magenta #FF4FD8, and warm white #F5F1E8; keep accents to 1-2 dominant highlights while allowing small warm amber stage-light sparks.
- Border/shadow: apply a subtle soft drop shadow behind the main title, around 4px y-offset, 12px blur, 15% opacity; feather stage haze and crowd silhouettes softly into the background.
- Typography treatment: crisp vector-like edges, strong kerning control, and a slight condensed fit for the footer to maximize information density.
- Poster realism: include small-scale production credits, sponsor text, ticket prices, QR-like code, serial note "POSTER NO. 2026-07", and venue guidance text while keeping all important Korean readable.
- Graphic details: use thin divider rules, micro labels, scanline texture, halftone dots, subtle paper grain, and neon glow overlays to create a realistic premium festival print.

[5. VISUAL STYLE]
- Camera / lens: cinematic wide 24mm look with a shallow depth of field feel, as if shot on a Sony A7R IV with a 24mm f/1.4 lens for the background atmosphere, while keeping the typography razor sharp.
- Lighting: stage backlight mixed with city glow, using cool light from the upper-right and a faint rim light on silhouettes; add magenta side light, cyan laser beams, warm stage bulbs, and glossy haze for a real outdoor concert mood.
- Color grade: high-contrast night palette with electric blue, violet, and pink highlights over a charcoal base, similar to a modern music-festival teaser poster.
- Print finish: subtle matte paper texture with slight ink density variations, gentle glow bloom around neon graphics, and clean digital-poster sharpness for social media readability.

[6. MOOD]
Premium Korean music festival poster — a Seoul night event graphic with the energetic polish of a major concert teaser, the density of real event publicity, and the stylish finish of contemporary editorial poster design.
It should feel like an actual poster someone would see at a subway station, record shop, campus bulletin board, or on an Instagram event announcement.

[7. CRITICAL]
- Korean text accuracy: "여름밤이 가장 짧은 사람들을 위한", "2026.07.18-19", "한강 노들섬 잔디마당"
- English text accuracy: "SEOUL SUMMER NIGHTS"
- Additional Korean poster text to render cleanly: "입장 16:00", "공연 18:30", "TICKET OPEN", "1일권 ₩88,000", "양일권 ₩149,000", "주최 서울라이브랩", "후원 문화도시서울", "문의 02-0000-2026", "우천 시 정상 진행"
- Layout invariants: the main event name must stay centered and dominant; subtitle must remain directly below it; footer must contain date, venue, and lineup in a clearly separated block.
- Typography must remain clean and fully legible, with no broken Korean characters or accidental letter distortion.
