Create a brand-new Japanese settlement promotion square discount poster.
Accurately display the text “決算 SALE”“最大70%OFF”“15,000円購入で1,500円OFF”“20,000円購入で2,500円OFF”.
Use navy blue, mint green, coral orange, creamy white, and mustard yellow.
Arrange two clear tiered discount coupons beneath a massive 70% discount.
Employ bold geometric fonts, coupon cutouts, and subtle halftone decorations.
Ensure all Japanese text remains readable without adding extra fine print.
Do not include any brands, logos, URLs, QR codes, or watermarks.
Output a high-quality static PNG.
