9/// A platform-native video player widget.
10///
11/// The video is rendered by the platform's native player and embedded into the
12/// Fission layout as an opaque surface. Use [`BuildCtx::video_controls`] to
13/// create play/pause/seek action envelopes.
14///
15/// # Example
16///
17/// ```rust,ignore
18/// Video {
19///     source: "https://example.com/clip.mp4".into(),
20///     width: Some(640.0),
21///     height: Some(360.0),
22///     autoplay: true,
23///     loop_playback: false,
24///     ..Default::default()
25/// }
26/// .build(ctx, view);
27/// ```
