/**
 * The question card: one question, its options, and two ways out.
 *
 * This is the pi implementation of the {@link AskUser} port. It owns the
 * terminal for the length of one question and gives it straight back - which is
 * why the interview can be driven from a slash command but never from a tool the
 * model calls: nobody can answer a question that is being asked inside a turn.
 *
 * Two entries are appended to the interview's card, exactly as Claude Code
 * does: **Other…** for a free answer, and **that's enough** to submit. The
 * second one is not a cancel - the answers already given still count, and the
 * brief is still written. `esc` means the same thing, so the reflex to escape
 * out of a dialog does not throw the conversation away - and for as long as a
 * card is up, `esc` means nothing else: the run's stop key is held, or the
 * interviewer who has to write the brief would be stopped by the same press.
 *
 * A flow's `ask` says more of its card, through {@link Asking}: a choice, a
 * yes or no or a free text, whether "enough" is offered and under which label,
 * and when it is not, `esc` is the run's stop, and the help line says so.
