CLI
The CLI is an optional adapter over the same engine as Studio. It is not shipped. A person does not need it to open Studio. The library is a scene graph and cameras, with frame-exact timelines and compositions. The render stays SVG.
The package name is @modootoday/svgif-cli. The design commands are validate, migrate, describe, compile, export, new, and embed. Stdout is one JSON document. This snapshot does not publish the binary.
compile names the backends css-external, css-embedded, and smil. export names svg and html in-process. webp, webm, mp4, and gif need a local browser. There is no product server.
