Black Friday Mega Promo Sale Poster

[Format] Professional Black Friday e-commerce sale poster, tall vertical 9:21, energetic 3D-mascot gift-box stage style in red and gold. [Colors] Background is a vibrant red-pink gradient with radiating light and confetti; the headline is yellow-outlined white caps over chunky red-yellow type; the giant gift box is glossy red with a gold bow; the mascot is a white duck in a red hoodie; the benefits card is cream with red pills and gold coins. No frame border. [Layout] The date ribbon banner sits under the top headline cluster; a colossal red gift box with an open gold bow forms the backdrop of the middle; the duck mascot struts centre-frame holding a sign; two envelope mascots dance at the sides; a yellow band introduces a cream benefits card with three offer rows; a footer strip with address, phone and QR closes the bottom. [Subject] No people. A cheerful white 3D duck wearing blue swim goggles on its head, a red hoodie with "GO BF" print, a blue crossbody bag and red sneakers, striding forward while holding a yellow sign reading "GO GO!"; two smiling red envelope mascot characters with gold medals bounce at each side; gold coins and confetti rain down. [Headline] Top: "BLACK FRIDAY" in yellow-outlined caps, then "MEGA PROMO" in huge red-yellow chunky caps. Yellow ribbon: "Nov 24 - Dec 1". Yellow band: "Stacked Black Friday Perks, All For You". Card rows: "Free Lucky Draw — Win Your Whole Order Free, Enter Now", "Free $50 Home Credit Per Order", "$9.9 Add-On Buy On Store Bestsellers". Footer: address placeholder, phone number placeholder and QR code. [Mood] Zippy, mascot-driven and reward-heavy; a red-gold shopping carnival with sprinting-duck enthusiasm.
