Sweet & Cool Black Friday Neon Sale

[Format] Professional Black Friday e-commerce sale poster, vertical 9:16, retro neon-livestream style in magenta and violet with a moody stage room. [Colors] Dominant neon magenta and deep violet (#8a18a8 range) over dark striped wallpaper; glowing pink tube signs, a dripping neon heart and a warm floor-lamp glow; the header pairs a glowing pink script with chrome 3D caps; the offer banner is a white-outlined neon pill; footer text is pink and violet. No frame border. [Layout] Top quarter: script "Sweet & Cool" with stars over big chrome caps and a chain-link neon banner; the middle is a retro stage set — striped wallpaper, a neon "NO.1" shield sign and a tall neon menu board at the left, a dripping neon heart and framed print centre, a vintage TV on a dark console, a floor lamp, a neon phone-booth shelf at the right, palm leaves and vinyl records; a dark service strip and a pink sign-off line run along the bottom. [Subject] No people. The neon room itself is the subject: a retro television with static glow, a gramophone, a radio and stacked vinyl records create a vintage-cool broadcast set. [Headline] Pink neon script "Sweet & Cool" over chrome caps "SWEET-COOL LOOK SPECIAL"; neon banner: "Storewide From 50% Off - Buy 3 New Arrivals Get 1 Free"; neon menu board: "Stream Exclusive", "Mystery Box 2-Pack $99", "Was $299", red pill "Grab It Now"; side neon tags "Follow & Join Free"; footer icons: "7-Day No-Reason Returns", "Shipping Insurance", "Express Dispatch"; pink sign-off "BF NIGHT #SWEET-COOL SIGNAL". [Mood] Retro-cool nightlife swagger; magenta neon glow wrapping a vintage stage for a trendy fashion drop.
