Create a brand-new vertical poster for a Korean-language summer coupon pack.
Accurately present the text “여름세일 쿠폰팩”“COUPON 15%”“COUPON 25%”“COUPON 45%”“2026.08.05-08.20”.
Use plum purple, coral orange, mint green, cream white, and navy blue.
Arrange three coupons with torn edges vertically, complemented by scissors, tape, and sparkling bubbles.
The Korean title and discount amounts must be bold and clear.
Employ high-energy paper art collage while maintaining appropriate spacing between coupons.
Do not include any material watermarks, brand names, logos, website URLs, QR codes, or random small text.
Output a highly finished static PNG image.
