printNavHint static method

void printNavHint()

Print a one-line hint at the top of every wizard step so the user always knows how to retreat. Idempotent — call this freely.

Implementation

static void printNavHint() {
  stdout.writeln(
    '  Tip: type \u201Cback\u201D (or \u201Cb\u201D / \u201C<\u201D) at any prompt '
    'to step backwards \u00B7 \u201Cquit\u201D to abort.',
  );
}
