Create a new original English promotion poster with a multi-day deals headline.
Style: bold editorial paper collage, broad strips, curved corner labels, sparse starbursts.
Layout: tall portrait with a top event title, huge purchase discount, and extension rule at the bottom.
Main text: "7 DAYS OF DEALS", "SAVE 20%", "YOUR ENTIRE PURCHASE", "NO EXTENSIONS".
Language: English only; keep every phrase correctly spelled.
Design changes: use cobalt, pale peach, chartreuse, and cream with a new top-to-bottom rhythm.
Background: layered torn paper in cream, blue, peach, and chartreuse.
Remove: watermark, brand logo, QR code, website, author mark, and fine print.
Avoid: exact copying, original colors, random tiny text, misspelled text, and copyrighted brand elements.
