HyperFrames (video from HTML, made for agents)

The agent writes an HTML page with animations and HyperFrames renders it to MP4, frame by frame, the same way every time. For an agency that opens up social videos, intros and explainers that are edited like code: changing a client's text or color is changing one line, not redoing the project in an editor. Install it with `npx skills add heygen-com/hyperframes`; the base skill group is enough and the rest install on demand. It is maintained by HeyGen, which sells its hosted product on top, but the framework is Apache 2.0 and renders on your machine with its CLI.
