/**
 * The CLI's prompts, guarded against input that is gone.
 *
 * Inquirer does not settle a prompt whose input goes away: readline closes
 * (end of input, or the ^D a pty sends when its own stdin is /dev/null),
 * the event loop drains, and Node exits 13 with "unsettled top-level await"
 * (`vana login`, 2026-10-05). Every prompt goes through here instead, so
 * that is an answer: a yes/no question takes "no", the non-interactive
 * path; a question with no safe answer throws PromptInputClosedError, which
 * the CLI reports cleanly.
