Black Friday Electronics Mega Sale

Professional Black Friday e-commerce sale poster, tall vertical 9:21, bold red electronics mega-promo style with 3D emoji props. [Colors] Background is a saturated fire-red (#e02020) with darker red diagonal streaks and glowing yellow energy lines; headline type is red-outlined white with yellow accents; offer pills are white with red and yellow text; the bottom strip is deep red with white type. No frame border. [Layout] The top quarter stacks a two-line display headline with a small yellow script tag at the upper right; the middle zig-zags a staircase of white offer slabs down the right side, interleaved with a 3D megaphone on the left, a winking 3D emoji sun and a smiling 3D flower; the lower third presents the product cluster in front of a white rounded panel; a thin footer strip closes the bottom with a pill, a footnote and a QR block. [Subject] No people. A white triple-camera smartphone standing upright beside an open champagne-gold laptop, with white wireless earbuds in an open case in front; glossy studio reflections, clean product photography cut-out on the red ground. [Headline] Top, two heavy tilted lines: "BLACK FRIDAY MEGA SALE" in huge white caps with red inline shadows, then "NOW ON!" in gold italic caps with a yellow swoosh underline; a small yellow script tag "Happy Shopping" sits upper right. White slabs, in reading order: "Instant Rebate" above "Up To $500 Off"; "Hot Sellers" above "Flash Price $2,999"; "Trade In" above "Enjoy 25% Off"; "Buyer Protection" above "Price-Drop Guarantee". [Badges] Bottom strip: a white search pill reading "Join Our Group For Extra Perks", a footnote line "*Ask shop support to claim perks" and a small QR code block at the right. [Mood] Loud, urgent and tech-forward; blazing red and gold with playful 3D emojis driving a deal-by-deal staircase.
