Create an ultra-wide 3:1 panoramic desert landscape with sweeping orange sand dunes under a pale blue sky. The scene is minimal and cinematic, featuring one small lone palm tree near the lower center, standing in a shallow basin between dunes. A massive smooth dune rises in the background, its crest sloping gently upward, with warm late-afternoon sunlight illuminating the sand and casting a broad soft shadow across the right side of the large dune. The foreground contains layered rolling dune ridges with subtle wind-shaped curves and delicate highlights. Use a realistic photographic style, soft natural lighting, warm peach and terracotta sand tones, slight atmospheric haze, calm empty wilderness mood, no people, no buildings, no text.
