Black Friday Gift Extravaganza Sale Poster

Professional Black Friday e-commerce sale poster, vertical 9:16, grand red stage style with gold 3D lettering and fireworks. [Colors] Background is a deep red stage curtain gradient (#a00d0d to #4a0404) with golden fireworks bursting at the top corners and a soft black central void; the headline is chunky gold 3D caps with red keylines; the subline pill is bright red with white type; the side card is white with red tabs; the bottom sweep is a glowing gold ribbon; trust badges are white pills with red seals. No frame border. [Layout] The top quarter stacks the gold 3D headline over a red rounded subline pill; the centre of the frame stays dark and empty for product insertion; a white promo card hugs the left edge mid-frame with two stacked red-tabbed offers; a sweeping gold ribbon curves across the lower third; a full-width row of four white badge pills anchors the bottom; a small logo placeholder sits top centre. [Subject] No people. Fireworks, light streaks and a reflective gold ribbon are the only decorations; the dark centre is reserved as clean product space.
