Stone Watermill at Autumn Dawn (Image-to-Video Animation)

Start from the step 2 image "Stone Watermill on a Forest Stream at Autumn Dawn" as the exact first frame, and animate it into a calm ${duration:6}-second cinematic shot. Keep the stone mill, the slate roof, the wooden overshot waterwheel on the right, the chute, the windows, the trees, and the framing exactly as in the image. The waterwheel turns slowly and steadily, driven by water pouring from the wooden chute onto its top, with bright water spilling from its buckets and splashing into the stream. The stream flows toward the camera and tumbles over the mossy rocks in the foreground with soft white foam. Low mist drifts slowly across the water from left to right. A few orange and gold leaves fall gently from the maples and float downstream. Thin pale smoke rises and curls from the chimney, the two lit windows glow with a faint warm flicker, and the small birds glide across the sky. Golden dawn light slowly brightens. The camera makes one very slow, smooth push-in toward the mill. Natural, realistic motion, no cuts, no new objects, no people, no text.
