Solitary Wooden Signpost in a Tranquil Desert

Photorealistic wide-angle image of a solitary wooden signpost standing in an arid desert beneath a clear blue sky. The post is weathered and sun-bleached with faded paint and rough splinters. Cracked, sandy ground with sparse shrubs and scattered rocks stretches to a distant dune horizon. Bright sunlight creates crisp shadows; a subtle heat haze shimmers on the horizon. The signpost is slightly off-center, horizon low, emphasizing vast, tranquil open space and quiet atmosphere. Color palette blends warm desert tones (ochre, tan, burnt sienna) with a vivid azure sky. No people or animals; mood: calm, peaceful, contemplative.
