提示词Panoramic fine art cityscape wallpaper, a graceful modern coastal city skyline at dusk reflected in still water, illuminated warm amber windows, deep teal blue evening sky occupying half the image, sparse soft clouds, subtle architectural details, balanced horizon across the lower half, wide immersive cinematic composition, calm and sophisticated, no people in foreground, no readable signs, no text, no watermark, no borders.
Target: Ultrawide wallpaper, 21:9 aspect ratio.
