Prompt
A very soft three-tone gradient spanning a 16:9 canvas, horizontal orientation with left-to-right tonal flow and subtle diagonal tension to avoid flatness. The composition keeps all important visual transitions inside the 16:9 frame and preserves full-bleed edges with no visible seams, with the center remaining gently muted and balanced. Colors transition almost invisibly between a deep slate, a cool mid-teal, and a pale silvery blue with a faint fourth highlight near the right edge for a quiet punch. Keep gradients micro-blended to eliminate banding and maintain smooth chroma drift across the width. Add a whisper of paper-like micro-texture at very low opacity to prevent perfect flatness while remaining visually unobtrusive. Deliver a clean vector-style rendering suitable for UI backplates and wallpaper export with even luminance and no hard edges.
