Add @karnstack/kino/youtube — kino's glass chrome over the YouTube IFrame Player API. <YouTubePlayer videoId="…" /> plus createYouTubeProvider and a parseYouTubeId helper that accepts a bare id or any watch / youtu.be / embed / shorts URL. No runtime dependency; the API is loaded on demand. Play/pause, seek, speed, volume, fullscreen, keyboard map, and a captions menu (driven by the video's own subtitle tracks, rendered by YouTube inside the embed) all work through kino's controls. Buffering is mapped to "not paused" so a stall doesn't read as a pause. controls:0 plus pointer-events:none on the iframe keep YouTube's hover chrome and second progress bar from showing. Follows YouTube's API terms — plays through the official IFrame API and does not obscure the player, so YouTube's own thumbnail, play button, title, and logo show before playback and while paused. Quality, picture-in-picture, and scrub-preview storyboards are hidden because the IFrame API doesn't expose them. Docs/demo: reframe the README away from "Mux is the first provider" to three shipped providers (Mux, Native, YouTube), add a YouTube section and props, mark YouTube shipped on the providers page, and add a YouTube tab to the live studio.
