Should explain what it means for the property to be present or missing.

Other than the MSTG/VTG issue, looks ok.

const videoTrack = stream.getVideoTracks()[0];
const blurIndicator = document.getElementById("blurIndicator");
const trackProcessor = new MediaStreamTrackProcessor({ track: videoTrack });
const trackGenerator = new MediaStreamTrackGenerator({ kind: "video" });

You need to use the standardized API (VideoTrackGenerator)
