+// Run starts the full-screen TUI and blocks until the user quits (Ctrl+C /
+// Ctrl+D) or the program errors. It is the alt-screen counterpart to repl.Run:
+// cmd/pigo's dispatch calls it on the (no prompt + TTY + no --no-tui) path and
+// maps its error to the process exit code. The alt-screen is entered/left via
+// the View returned by the root Model, so a clean return here restores the
+// terminal to the user's prior scrollback.

+	// entering the alt-screen, mirroring repl.Run: a store/resume failure is a
+	// clean pre-launch error rather than a broken interactive session.
