Black Friday Neon Dollar Sale Poster

[Format] Professional Black Friday e-commerce sale poster, vertical 9:21, neon cyber-city night style in electric blue with a giant glowing dollar centrepiece. [Colors] Background is a deep blue-purple neon cityscape (#2b2f8f range) with glowing signboards, light trails and floating coins; headline type is hot pink with white and gold outlines; the giant centrepiece glows magenta-gold; coupon banners are cream with blue and red text; the bottom button glows blue. No frame border. [Layout] A thin vertical tag hangs down the top-left edge reading "Annual Best-Price Event". The headline stack occupies the top third, followed by a purple time pill and a row of three small deal tags. The middle two-thirds are dominated by a giant 3D dollar sign radiating light rings above a swirling street intersection, with coupon banners tucked at its sides. The bottom strip holds the sale dates, a glowing button, a phone line and a QR code. [Subject] No people. A colossal glossy magenta-gold 3D dollar sign "$" stands centred like a monument, emitting pink energy rings over the neon crossroads; tiny cars and pedestrians light the streets far below. [Headline] Top-centre: "BLACK FRIDAY" in enormous hot-pink rounded 3D caps with a white outline and blue drop shadow, then "SUPER SUBSIDY" in pink 3D caps with gold trim; beneath, a purple pill with a lightning bolt reads "Opens tonight 8 PM" in white. A row of three blue tags: "Cross-Store Savings", "Flash Deals", "Order & Win Prizes". [Badges] Cream ribbon banners: "$150 Off $800" on a curved ribbon at the lower left and "$50 Off $300" at the upper right. Bottom strip: "Sale dates: Nov 24 - Dec 1", a blue glowing button "Lock In Deals >", a VIP phone line and a small QR square. [Mood] Electric, game-like and extravagant; a blue neon night built around one giant glowing dollar.
