The authored title of the figure lobby's focused subplot, or '' when the
subplot has no authored title. The subplot's title is stored on its active
trace; placeholder defaults are rejected via isAuthoredTitle. The
!state.subplot guard is defensive so a malformed figure state cannot crash
callers. Shared by the lobby navigation text (TextService) and the exit cue
(subplotCue) so the traversal is defined once.
