Black Friday Mega Sale Poster

Professional Black Friday e-commerce sale poster, vertical 9:16, bright calendar-wall sale style with a red shadow-box shelf of gifts. [Colors] Background is a white tiled wall with large light-grey calendar dates; the headline is red brush 3D with a red swoosh underline; the recessed shelf is warm red with soft inner shadow and a spotlit glow; products are cream, white and beige; the bottom banner is a red diagonal ribbon with white and yellow type; the button is solid red. No frame border. [Layout] The tiled wall shows oversized grey numerals "21" top-left and "25" top-right, a red exclamation accent, and a large "27" on the mid-left edge; the headline spans the upper third; the centre-right is a deep red shadow-box nook holding the gift still-life with two hanging red calendar tabs reading "NOV 27"; a red diagonal ribbon crosses below with the offer line; a white claim strip and a big red pill button close the bottom. [Subject] No people. A recessed red display nook styled like a gift cupboard: white over-ear headphones, cream gift boxes with red satin bows, a slim white insulated bottle, small cream jars and a folded beige knit towel on a red shelf; soft spotlight from above. [Headline] Red brush-script caps on two lines: "BF MEGA SALE" and "YEAR'S LOWEST PRICES" with a red swoosh beneath. Red ribbon in white and yellow: "Stackable Savings, Up To 50% Off". White strip: "Curated Picks | Limited-Time Drops | Stock-Up Deals" with small red icons. [Badges] Big red pill button at the bottom: "Shop Now" in white caps. [Mood] Crisp, calendar-driven anticipation; clean white tiles framing a warm red gift nook at the year's best prices.
