Create a brand-new English-language summer weekend promotion vertical poster.
Accurately present the text “SUMMER SALE”“FRIDAY 20% OFF”“SATURDAY 30% OFF”“AUGUST 28-29”.
Use plum purple, teal green, warm yellow, cream white, and black.
Place a universal megaphone in the upper-right corner, letting ribbon-like sound waves flow toward two large coupons.
Friday and Saturday discounts must be clearly separated and suitable for mobile reading.
Employ lively paper-cut layers, bold fonts, and balanced, safe margins.
Do not include brands, logos, URLs, QR codes, watermarks, or fine print.
Output a high-completion static PNG.
