提示词A vast, low-key seascape dominated by massive, smoothly textured charcoal basalt waves. The waves are arranged in a dynamic, horizontal flow across the frame. A single, intense warm bronze rim light traces the crests and edges of the rock, separating them sharply from the deep, velvety black background. The composition is centered, emphasizing the powerful curves. Photorealistic, high contrast, restrained palette of black, charcoal grey, and warm bronze. Wide 16:9 wallpaper; subject off-center, quiet low-contrast outer margins for desktop icons. Full-bleed artwork, no border, no frame, no text, no typography, no logos, no signature, no watermark.
