A sleek, minimalist call-to-action poster background. Deep black background with a soft, wide gradient glow at the bottom blending from deep teal (#0D7377) on the left to vibrant turquoise on the right. A subtle, thin orange horizontal line across the middle third of the image. No objects, no bottles, just pure abstract lighting and gradient. Clean, premium, high-end aesthetic, Apple-style simplicity, vertical 9:16 aspect ratio. NO TEXT — the entire image is a background for typography overlay. Leave the center 50% of the image completely empty.
