Build me a simple app and command line workflow for making videos from HTML, CSS, images, and animations.

I want to be able to write a normal web page, preview it, and render it into a deterministic MP4 video locally. It should feel easy for an AI coding assistant to use, so include a clear setup flow, a few good starter examples, and a smooth way to update or install the right skills. If it makes sense, add a small studio or playground experience too, so I can see the result before exporting it.

Please make the default experience focused on a quick intro video or motion graphic, with text, media, captions, and subtle animations. I’d like it to work well on my machine without a lot of manual steps, and if you need current docs or best practices, look them up online.
