Accurately display the text “무한지급 쿠폰”“SPECIAL COUPON 20%”“MOBILE SALE COUPON”“2026.08.01-08.31”.
Use coral orange, mint green, cream white, violet, and black.
Design a vertical coupon dispenser, with one large coupon sliding out from the center.
Add paper-tearing strips, perforations, and small abstract discount tags.
All Korean and English text must be bold and clear.
Do not include barcodes, coupon numbers, app names, brand names, website URLs, QR codes, or watermarks.
Output a high-quality static PNG image.
