Jupyter / Non-blocking Viewing

scene.show() starts a viewer on a background thread and returns immediately, instead of blocking like SimViewLauncher/SimViewServer.run. This is handy in a notebook: evaluating the returned handle as a cell's result embeds the viewer inline via an iframe.

handle = scene.show()  # non-blocking; scene itself is left untouched
handle  # in Jupyter, displays the viewer inline (uses _repr_html_)

# ... do other work, or just let the cell above stay interactive ...

handle.stop()  # or: `with scene.show() as handle: ...` to stop automatically

See the ViewerHandle API reference for the full behavior.
