Cinematic Fire Effect Asset

Create a high-resolution VFX fire effect asset: a wide horizontal wall of intense flames rising from the bottom edge across the full width of the frame, on a pure black background. The fire should have bright yellow-white cores, saturated orange and red outer tongues, and semi-transparent smoky heat wisps fading upward into darkness. Use {argument name="flame height" default="tall varied flame peaks"} with uneven curling shapes, including several large twisting flame columns at the left, center, and right, plus a dense low band of smaller flames along the base. Add many glowing ember particles and sparks drifting upward, with tiny red-orange specks scattered above the flames. Make it look like a realistic cinematic game effect or compositing element, high contrast, sharp detail, natural turbulent motion implied, no objects, no text, no people, no border, centered composition, {argument name="background color" default="pure black"}, {argument name="fire color palette" default="yellow white orange red"}, {argument name="aspect ratio" default="16:9 wide landscape"}.
