提示词A solitary adult road cyclist is captured rounding a sweeping curve on smooth, matte charcoal gray asphalt. The scene is set at dawn, with soft, ethereal mist hanging low over the ocean in the background. The cyclist is rendered as a clean, dark navy silhouette, wearing a completely blank, solid-colored jersey and riding unbranded equipment. The lighting is dramatic backlighting, casting a subtle rim light on the rider. Photographic medium, restrained palette of charcoal, navy, pale blue, and soft gray. Intentional negative space emphasizes the curve and the horizon. 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.
