Solar Desert Civilization Poster Prompt — Futuristic Worldbuilding

Design a cinematic key-visual poster for a futuristic desert civilization run entirely on solar power. WORLD: a vast sun-baked desert city where gleaming solar-panel towers, mirrored heliostat fields, and sand-colored domed architecture rise from the dunes in one cohesive design language — warm sandstone, burnished gold, and deep solar blue. PEOPLE: desert-robed travelers in flowing sun-shielding garments with solar-woven trims cross a plaza on a sleek sand-skimming vehicle, small against the monumental architecture to sell the scale. DETAILS: weave in the civilization's visual system — sun-disc emblems, geometric shade screens, glowing energy conduits tracing the streets, and a hand-drawn-style map strip along one edge. LIGHTING: blazing desert sun with long shadows, heat haze on the horizon, and golden-hour glow on the solar arrays. STYLE: cinematic realism, ultra-detailed, epic scale, poster-grade composition with a clear focal point and generous sky for a title.
