• examples/dashboard runs the real full-screen TUI against an in-process
  demo engine — no model, no network, no source of your own. The article
  streams in word by word, so the queue, phase markers, live preview,
  progress bar, and focus timer animate exactly as they do on a real run.
  It is the quickest way to see the interface or check the layout at a
  given terminal size.
