Write an ad storyboard for наушники для тренировок for Reels и Shorts. Beats, in order: hook, proof, benefit, call to action. For each beat give the seconds, the frame, what it must prove, and the on-screen text. Rules: one action per beat; product, person, and background each have one job in frame; keep the user's own line if they supplied one, no ad clichés; never invent product characteristics that are not in the input; the call to action is one action only.
