The creator found the use case that reframes the feature: a moment of privacy while the webcam is
on. A blur that can only cover the desktop cannot do that.
- SceneCompositor applies the blur group AFTER every element is composited (still before the
flash / social bar / ticker / zoom overlays), so it covers webcam, chat, alerts — anything. Its
position in the layer list no longer affects the output, so it is added at the top and the
reorder clamp is gone.
- Supersedes the earlier "blur sits below the brand" rule: a universal blur does obscure the logo
when it covers it. Called out in frame-pipeline.md so it is not re-litigated.
- Preview mirrors it exactly: the blur host moved OUT of CanvasGrid to a sibling above it, so the
VisualBrush samples every layer (and cannot sample itself). It used to sample only the backdrop,
which is why a circle over the webcam would have shown sharp pixels in the editor and blurred
ones in the stream.
