I want to make a 15-second vertical short video for Channels. Please write a storyboard script for me, listed in a table: shot number, duration, visual content, camera movement, subtitles.
Requirements:
1. 4 shots, each 2–5 seconds, the first shot grabs attention within 2 seconds;
2. "Visual content" written as a description that can be used directly to generate images: subject, scene, style, lighting;
3. Camera movement only uses these: push in, pull out, pan, orbit, overhead shot;
4. Each subtitle no more than 10 characters, the last shot shows the product name and a call to action.

What I want to shoot is: [product or event, e.g.: our new ergonomic chair]
