Heat shimmer ripples across the sunbaked cracked clay, while violent gusts of wind whip plumes of fine vermilion sand across the undulating dune crests. The camera executes a slow, cinematic drone orbit, climbing gradually higher as golden-hour sunlight flares intensely off the building’s razor-sharp glass-and-copper edges, casting a towering, lengthening shadow across the arid expanse. The audio is dominated by the deep, hollow drone of desert gale howling over metallic vents, punctuated by the sharp, continuous hissing of drifting sand grains scraping against polished stone.",
