FAQ

Can I change the labels after rendering?

Yes. The HTML and CSS remain editable, so you can revise copy, timing, and column placement before rendering again.

Does this skill generate images or use online fonts?

No. It builds the composition with HTML and CSS, uses offline system font stacks, and renders the video locally.
