Create a brand-new square special-offer poster in Japanese for advertising and marketing.
Accurately display the text “特別オファー”“最大70%OFF”“9,999円以上で送料無料”.
Use deep plum purple, mint green, coral orange, warm cream color, and black.
Center the design around an oversized 70% discount, complemented by layered rounded-corner cards and a delivery-box icon.
Restructure the horizontal information into a spacious, well-balanced square format.
All Japanese text should remain large, sharp, and easy to scan.
Do not include any brands, logos, URLs, QR codes, watermarks, or fine print.
Output a high-quality static PNG image.
