+and customizations breaking.  Because NbClassic provides the classic interface
+on top of the new Jupyter Server backend, it can coexist with other frontends
+like JupyterLab and Notebook 7 in the same installation.  NbClassic preserves
+the custom classic notebook experience under a new set of URL endpoints, under
+the namespace @code{/nbclassic/}.")
