Violet Dunes — Twin-Sun Desert Crossing

A 10-second 16:9 exoworld sequence: crossing an alien dune sea under twin suns. The scene opens on the violet sand, the sky teal, every rock casting two shadows at slight angles, the drone surfing the dune crests as the smaller sun begins to set. 0-4s: The drone rides the crests, the violet sand rippling in alien patterns, the light shifting to alien-rose as the small sun dips, the two shadows of each rock slowly converging; strange sail-plants tack across the dunes on the wind, their membranes billowing. 4-7s: The surf continues over a vast slip face, the sand cascading in violet streams, a herd of six-legged grazers moving in the distance, undisturbed, their double shadows tracking them; the sail-plants veer, catching a gust. 7-10s: The drone rises off the last crest, the dune sea spreading to the teal horizon, the small sun half-gone, the rose light deepening, the grazers small dark shapes in the violet vastness. The small sun's last sliver flares green for an instant on the horizon — an alien flash. The grazers' double shadows merge into one long smear as the light dies, and the sail-plants furl their membranes for the cold night.
