+Scenes storyboard passthrough: `ScenesProviderOptions` (and therefore
+`ScenesPlayer`) accept `storyboard: { vttUrl }`, surfacing
+`capabilities.hasStoryboard` and `state.storyboard` so the scrubber shows
+thumbnail previews on hover, exactly as it does for Mux sources. The VTT's
+cues point into a sprite image via `#xywh` fragments (the same format the Mux
+storyboard track uses). `SceneManifest` gains an optional `storyboard` field
+recording where that VTT lives.

 Captions are a sidecar VTT fetched and rendered by the parent in kino's own caption overlay, so the host page never deals with text tracks.
 
+Storyboards work the same way: pass `storyboard={{ vttUrl }}` and the scrubber shows thumbnail previews on hover, exactly as it does for Mux sources. The VTT's cues point into a sprite image via `#xywh` fragments (the format Mux storyboard tracks use); whatever produces the sequence generates both files, kino only fetches the VTT and paints the tiles while you scrub. As with `src`, the URL may carry an auth token, already encoded by the caller.

 kino sets `allow="autoplay; fullscreen"` on the iframe it creates. That delegates the parent page's user activation (the click on kino's play button) into the frame; without it, `audio.play()` inside the host is blocked by autoplay policy. If your app itself runs inside an iframe, the outer frame needs the same `allow` list.
