Shared Dataset Proof

Two viewers reuse one DatasetSession. The left pane can free-roam in shell mode while the right pane stays as a reference view. Both mount automatically; use the snapshot JSON below if you need to inspect bootstrap / warm state.

Both viewers share render bootstrap, root-shard warming, and cache stats.
The left pane uses CameraRigController in ObserverShellField mode.
The right pane keeps the cartoon profile plus Orion constellation art.
The selector switches both panes between shell-based and target-locked loading.
