Create a new original coupon or sale design: graphic Black Friday promotion with torn-paper or label-like typography, strong contrast, and geometric framing.
Style: clean commercial graphic, polished and print-ready, with harmonious burgundy, powder blue, and ivory.
Layout: Vertical poster composition preserving the source-like hierarchy of headline, large value, supporting line, and date while using entirely new shapes and spacing.
Main text exactly: "기간 한정 세일", "40% 할인", "유효기간 2026.09.30".
Language: Korean and English; keep that language and script only, preserve its natural typographic hierarchy, and do not translate.
Design changes: use a different dominant palette, rearrange icons and patterns, and redesign borders, corners, perforations, shadows, gradients, and decorative angles.
Background: Use a newly colored commercial backdrop with no copied texture or decoration.
Remove every brand, store or platform name, logo, watermark, website, QR code, author mark, barcode, and any note beginning with "*".
Avoid exact copying, original colors, copyrighted elements, random text, tiny unreadable legal text, misspellings, fake logos, and scannable codes.
