Saves accumulated segments after every chunk. On page refresh or crash,
reopening Cast as Audiobook for the same document restores the session
automatically — shows a banner with completion % and save age.
Manual speaker reassignments in the cast view are also autosaved so
review corrections survive a refresh. Draft clears when the script is
saved to Script Rehearsals or a fresh Recast All is triggered.
