Black Friday Mega Shop Livestream Studio Poster

[Format] Professional Black Friday e-commerce sale poster, vertical 9:21, modern livestream-studio style with crystal numerals and a gold display stage. [Colors] A rich red backdrop at the top and bottom bands; a row of translucent red crystal 3D letters gleams behind the headline; the middle is a contemporary cream-and-gold showroom with curved white walls, a gold slatted wall with four floating shelves, warm cove lighting and a round white display stage; white and red display type; a red guarantee band at the bottom. No frame border. [Layout] Logo pill top-centre; the crystal letters line the very top behind a red slab headline and a white pill subline; the centre two-thirds show the empty studio: curved cream walls on the left, gold slat wall with staggered floating shelves on the right, ceiling spotlights and a glowing circular stage low-centre; a red band with three white guarantees anchors the bottom. [Subject] No people. A pristine modern livestream set: a round white podium stage with a soft under-glow, four gold floating shelves holding small display blocks, a curved white wall with hidden cove lighting, and warm spotlights in a cream ceiling; red crystal reflections shimmer along the top edge. [Headline] Red slab with white 3D caps "BLACK FRIDAY MEGA SHOP" set over the crystal letters "BF"; white pill with red caps "Every Night 8:30 PM, See You In The Live Room"; bottom red band with three white caps items: "Official Authentic", "Free Shipping Insurance", "Worry-Free After-Sales". [Badges] Three white text guarantees evenly spaced on the bottom red band. [Mood] Sleek, premium and appointment-viewing; a gold-lit showroom stage waiting for the nightly Black Friday live drop.
