+  # ==> Navigation configuration
+  # Lists the formats that should be treated as navigational. Formats like

+  # is mountable, there are some extra configurations to be taken into account.
+  # The following options are available, assuming the engine is mounted as:
+  #
+  #     mount MyEngine, at: '/my_engine'
+  #
+  # The router that invoked `devise_for`, in the example above, would be:

+  # config.omniauth_path_prefix = '/my_engine/users/auth'
+
+  # ==> Hotwire/Turbo configuration
+  # When using Devise with Hotwire/Turbo, the http status for error responses
+  # and some redirects must match the following. The default in Devise for existing
+  # apps is `200 OK` and `302 Found` respectively, but new apps are generated with

+  # Note: These might become the new default in future versions of Devise.
