//! Optional follow-up suggestions from `suggest_options` (#599).
//!
//! Non-blocking: buttons ride under the response and a tap injects the
//! chosen suggestion as a new turn. The action id only carries the option
//! index; the tap handler maps it back through the stored list. Cleared on
//! tap or when the user sends anything of their own.
