[Purpose]
K-pop fan sign event and concert merchandise mockup, four-item collage layout for a realistic promotional merch preview.
Use a polished fandom-goods editorial look with tactile product photography, printed labels, event information, barcode/SKU details, and coordinated packaging elements, suitable for social post, pitch deck, concert booth banner, or online merch announcement.

[Composition]
- A 4-item collage fills the full landscape frame, with each product occupying a separate panel and consistent scale across all panels.
- Use {아티스트·팬덤} as the central identity anchor across the set; make it feel like a real K-pop fan sign and concert goods drop with a unified visual system.
- Background treatment: {배경} with a premium studio merch-table / flat-lay presentation feel, including realistic paper cards, product tags, acrylic reflections, fabric texture, plastic packaging, and soft cast shadows.
- Maintain a balanced commercial layout with readable product hierarchy, natural spacing between items, and enough surrounding printed detail to feel like an actual merchandise preview board.
- Place {비율} as the intended canvas relationship; keep the collage structured for a wide horizontal presentation.
- Add a slim event-info header or footer strip with Korean details such as date, venue, ticket note, SKU/barcode area, and small fanclub-style credit text.

[Core Structure]
1. Main hero panel: place {아티스트·팬덤} branding as the dominant visual identity, with the most recognizable merch item front and center, preferably the lightstick shown with reflective plastic, glowing inner detail, wrist strap, box sleeve, and printed product tag.
2. Secondary panels: arrange the remaining {굿즈 4종} items in a coordinated four-part collage, each shown as a realistic merch mockup with consistent perspective and lighting.
3. Color system: apply {시그니처 컬러} consistently across packaging, accents, print details, product labels, sticker tabs, decorative dividers, and small highlight elements.
4. Logo application: integrate {로고·심볼} on apparel, packaging, accessory surfaces, hang tags, small label stickers, and corner badges with believable print placement and realistic scale.
5. Product realism: show material differences clearly — matte cotton weave and fold creases for apparel, terry/fiber texture for the towel, glossy acrylic/metal for keyring and badge details, and semi-translucent or reflective parts for lightstick details.
6. Presentation finish: make the layout polished like a professional fandom merchandise concept board, with printed item numbers, short Korean captions, subtle grid dividers, price/SKU microcopy, folded paper shadows, product wrappers, and a small barcode block.
7. Add realistic surrounding collateral: mini ticket stub, fan sign entry card, order sheet corner, small holographic sticker, and tiny caution/size labels, all coordinated with the same color palette.

[Style Rules]
- Typography: bold clean sans-serif such as Pretendard or Noto Sans KR for Korean labels, with medium-to-bold weight and clear hierarchy; small supporting text can use a lighter sans-serif at 18–24px equivalent.
- Color palette: {시그니처 컬러} with crisp white, soft cool gray, and restrained gold accents; use hex-equivalent direction like #1E4DFF, #FFFFFF, #D8B15A, and pale neutral gray for background balance.
- Border/shadow: subtle studio-style drop shadows with 4px y-offset, 14px blur, about 15% opacity; keep edges crisp and mockup-like rather than painterly.
- Graphic details: use thin dividing rules, rounded label chips, small serial numbers, barcode-like black lines, holographic sticker shine, and tiny product-spec text to make the board feel manufactured and photographed.
- Korean copy should be short and realistic, like actual merch catalog labels, not long marketing paragraphs.

[Visual Style]
- Camera / lens: professional studio product photography look, 50mm lens equivalent at f/8 for flat-lay clarity and accurate merch proportion.
- Lighting: even softbox lighting from upper-left at about 45°, with a gentle fill from the right to keep logos and fabric textures readable.
- Color grade: clean cool-white base with saturated blue, bright white, and metallic gold accents; controlled contrast, no heavy warmth.
- Rendering quality: high-resolution realistic product mockup, sharp typography, visible material texture, slight lens realism, natural contact shadows, polished acrylic highlights, crisp printed packaging, and believable folds on fabric items.

[Mood]
Premium K-pop fandom merchandise editorial — polished fan event preview with a BTS / SEVENTEEN fan-sign presentation feel, energetic concert anticipation, collectible goods excitement, and a real merch booth catalog atmosphere.

[Critical]
- Korean text accuracy: 반드시 다음 문구가 정확히 보여야 함: "NEW WAVE", "WAVERS", "01 응원봉 (라이트스틱)", "02 티셔츠", "03 응원 타올", "04 키링·뱃지".
- Also render short supporting Korean event details clearly: "팬사인회 & 콘서트 굿즈", "2026.05.18 SAT 18:00", "서울 올림픽공원 핸드볼경기장", "티켓 오픈 D-7", "MD 부스 운영 12:00–20:00", "ONLINE PRE-ORDER", "₩39,000", "₩45,000", "₩25,000", "₩18,000".
- Include small realistic microcopy such as "VOL.07 GOODS PREVIEW", "SKU NW-WV-2026", "model credit: WAVERS CREW", and a barcode/SKU area printed on the layout.
- All four merch items must appear as a cohesive set with consistent design language, unified scale, and believable product mockup realism.
- Keep the composition landscape-wide and clearly readable as a four-item collage.
