 /*
   Interactive new-player tutorial component driven dynamically by chapter Markdown files.
-  Streamlined terminal output: immediate MUD output execution without extra "Press Enter to carry on" pauses.
-  Clear end-of-tutorial handover options to Play Hub, Browser Client, or Newcomers Guide.
-  Features visual toggle pill indicator for Commands, unified Narrative vs Quest Action Card UX, and inline markdown formatting for commands in quest descriptions.
+  Streamlined terminal output with explicit Player State Machine transitions:
+  - AWAITING_COMMAND: User input active for required quest command.
+  - PAGING_OUTPUT: Terminal content overflows; paging down transitions to pending action.
+  - PLAYING_BEAT: Auto-streaming narrative story beat before next step.
+  - CHAPTER_COMPLETE: Final step completed, displays handover options card.
