What html-video is
html-video is the meta-layer that sits above all of them. You talk to your agent; it picks the engine, picks the template, fills in your content, and renders the video. The engine is an implementation detail behind a single adapter interface — one render(input, ctx) contract that any backend can satisfy. Add a new engine and every template, every agent, and the whole studio workflow get it for free. No new DSL to learn, no rewrite when you switch engines.
