Create a brand-new vertical Korean double-coupon hot-sale poster.
Accurately present the text “더블쿠폰 핫세일”“쿠폰 두 장으로 더 큰 할인”“25% + 15%”“2026.08.05-08.12”.
Use deep cyan, magenta, cream white, yellow, and black.
Form the main visual with two cross-torn coupon tickets and three-dimensional bold text.
Add abstract gold coin and heatwave shapes while keeping the overall composition fresh and uncluttered.
All Korean text must be large and sharp for quick readability.
Do not include brands, logos, website URLs, QR codes, watermarks, or small text.
Output a high-quality static PNG image.
