/pr-to-video Make a 30-second 1920x1080 feature-reveal video from [PR URL]. Lead with what users get, not the diff; show the key code change with the `code-diff` block for one beat only; end on version number + repo URL. No narration, kinetic captions instead. **Spectacle beat:** The added line in the diff ignites — a green light-sweep travels its length and the line blooms as the camera settles on it.
