Imagine a small camera preview inside the canvas: the current webcam feed becomes a live layer.
Choose the framing with `objectFit`. The default `cover` fills the frame and crops its edges; `contain` shows the whole feed, while `fill` stretches it to fit. `mirror` defaults to `true` and flips the image horizontally for a selfie-style preview. These are the two configurable props listed in the registry.
The webcam draws its own live image, so later effects apply to the feed. The browser needs camera permission, and the feed may be unavailable if there is no camera or another app is using it. Ask before turning it on and provide a fallback state.
When to use
Use it for selfie previews, interactive camera effects, or a visual demo on a device with a camera. Avoid it where camera access is unavailable or the user has not explicitly agreed to it.
