Create a brand-new Korean welcome-benefit square coupon poster.
Accurately present the text “처음이라면 WELCOME BENEFIT”“쿠폰 25%”“5,500원 쿠폰”“추가 10%”.
Use deep navy blue, coral orange, mint green, cream white, and violet.
Arrange three layered brush-texture coupons diagonally across a square canvas.
Korean and English text must be bold, high-contrast, and clearly readable.
Adopt clean, modern paper-art collages and small starbursts.
Do not include store names, brands, logos, URLs, QR codes, watermarks, or tiny text.
Output a high-quality static PNG.
