Create a brand-new English-language Black Week vertical promotional poster for advertising and marketing.
Accurately present the text “BLACK WEEK”“UP TO 45% OFF”“2026.08.21-08.23”.
Use a color scheme of electric blue, magenta, amber yellow, and black.
Utilize elliptical neon entrances, abstract footwear silhouettes, and gift tags to create a sense of space.
Place the headline and 45% discount at the visual center, maintaining high contrast.
The overall style should be avant-garde yet uncluttered, suitable for mobile placement.
Do not include any brands, logos, URLs, QR codes, watermarks, or fine print.
Output one high-quality static PNG file.
