+reasons: an unrecoverable error occurred in the app, the server went down, the
+user lost internet connection, or any other reason that might cause the Shiny
+app to lose connection to its server.  With shinydisconnect, you can call
+@code{disonnectMessage} anywhere in a Shiny app's UI to add a nice message
+when this happens.  It works locally (running Shiny apps within RStudio) and
+on Shiny servers.")
