Black Friday Mega Sale with Gold Monogram

Professional Black Friday e-commerce sale poster, vertical 9:21, glossy red-and-gold festival coupon style with a giant 3D metallic monogram. [Colors] Background is a radiant red gradient (#d21c24 range) with light rays, floating gold coins and silky ribbon arcs in the upper corners; the hero monogram is polished 3D gold; headline slabs are bright red with white and gold type; the coupon card is cream paper with red and gold figures; the gifts panel is white with red icons. No frame border. [Layout] A giant glossy gold 3D monogram fills the top quarter with ribbons threading behind it. Beneath, a red headline slab on two lines, then a slim gold-outlined banner. A cream coupon ticket dominates the middle: a notched stub at left and three coupon rows separated by dashed lines. Below, a red header plate sits over a white rounded panel holding three gift tiles. A date line and caption run along the bottom next to a QR code placeholder. [Subject] No people. Oversized polished-gold 3D letters "BF" with bevelled edges and mirror shine, wrapped by red satin ribbons and floating gold coins; a cream coupon ticket with scalloped notches; three glossy icons — a red money pouch with coins, a gold coin, and a red gift box with gold bow. [Headline] Red slab in heavy white caps on two lines: "BLACK FRIDAY MEGA SALE" over "SURPRISE PERKS SEASON", with a gold-outlined banner: "Claim Coupons First, Then Order". Coupon stub in red: "Big Coupons, Limited Grab". Coupon rows in red-gold gradient: "$50 Off $100", "$80 Off $200", "$80 Off $200". White panel header: "Triple Treats"; tile captions: "Top Up $500 Get $50", "Points Flash Deals", "Refer Friends, Get Rewards". Bottom: "Event: Nov 24 - Dec 1" and "Join the community for more surprises". [Badges] A small white QR code placeholder at the bottom right beside the date line. [Mood] Opulent, jubilant and deal-driven; radiant red and polished gold stacking coupon after coupon.
