Dune Horizon Glow

Prompt

A quiet desert landscape at sunset in 9:16 vertical orientation. The upper third features a fiery red-orange sun peeking through swirling hazy sand clouds. The bottom half is dominated by sweeping dunes with long shadows. High-resolution texture of fine sand grains. Lateral margins are low-contrast for icon legibility. Clean header area. No watermark, no logo, no signature, no text, no UI, no mobile screen, no device frames, no interface elements, no artifacts, no borders, no margins, no cropping, no cut-off parts.
