-- Gets the user interface (UI) Customization information for a particular
-- app client\'s app UI, if any such information exists for the client. If
-- nothing is set for the particular client, but there is an existing pool
-- level customization (the app @clientId@ is @ALL@), then that information
-- is returned. If nothing is present, then an empty shape is returned.
