Make a 12-second landscape nature trailer from these three selected photos, in this order: mountain lake, aerial forest, bison cow and calf. Use three calm shots with clean cuts, subtle motion and natural color. Keep the animals recognizable. No titles, logos, extra people or animals. Silent output. Return the MP4 and keep the original photos and exact generation prompt.

This is an authored example of a single user-facing text. It is not a captured WhatsApp or iMessage conversation. The three public-domain source photos stand in for a selected camera-roll album; they were not taken on one trip or read from a private device. The agent expanded this brief into the published generation request.
