Black Friday Carnival Gift Box Burst

[Format] Professional Black Friday e-commerce sale poster, vertical 9:21, glossy red gift-box reveal style with glowing numerals and ribbons. [Colors] A red-to-pink sky gradient with fluffy clouds at the bottom; a giant open red gift box with a gold bow erupts light and ribbons; beveled glossy red-gold 3D numerals glow inside the burst; a rainbow arc, hearts, stars, a percent ticket and a cart icon fly outward; a cloud-white card holds red type; a red CTA pill closes the frame. No frame border. [Layout] The headline and a yellow ribbon sub-banner fill the top quarter; the open gift box dominates the centre in a radial explosion of ribbons and prizes; a cloud-shaped white card overlaps the box's lower half carrying the deal figures; a clock pill, a thin date strip and a wide red CTA pill run down the bottom edge. [Subject] No people. A huge open red gift box shot from a low angle, its gold-ribboned lid flying, shooting out glowing beveled 3D letters "BF", a small rainbow, red hearts, gold stars, a red percent ticket and a tiny cart icon through a burst of light. [Headline] White 3D caps "BLACK FRIDAY CARNIVAL" across the top; yellow ribbon banner with red caps "Hot Picks You Can't Miss"; cloud card: giant red figures "From $9.9" beside red caps "Grab Best-Sellers"; red pill with a red alarm-clock icon reading "Tonight 8:00 PM"; thin strip "Nov 24 - Dec 1"; wide red pill button "Shop Now" with an arrow. [Badges] No badge row; the alarm-clock pill and CTA button close the composition. [Mood] Explosive, magical and countdown-charged; one gift box detonating Black Friday deals into the sky.
