Desert Caravanserai at Dusk (Image-to-Video Animation)

Start from the step 2 image "Sandstone Caravanserai with a Camel Caravan in the Desert at Dusk" as the exact first frame, and animate it into a calm ${duration:6}-second cinematic shot. Keep the square sandstone caravanserai with its two round crenellated towers and tall arched gateway in the center-right, the three palm trees beside the right tower, the low dunes, the orange-to-violet sky, and the framing exactly as in the image. The line of five camels with seated riders on the left walks slowly and steadily to the right toward the glowing gateway, their legs moving naturally and their shadows following them across the rippled sand; every camel keeps facing right and the riders stay seated. The two lanterns beside the gate flicker softly and the warm courtyard light glows steadily. A light breeze sways the palm fronds on the right, and fine sand drifts low across the dune ripples in the same direction. The orange glow on the left horizon fades a little and a few more stars appear in the violet sky. The camera makes one slow, smooth push-in toward the gateway. Natural, realistic motion, no cuts, no new objects, no text. Quiet desert wind and soft camel footsteps.
