/**
 * User-facing copy for the dashboard chat (PTY) connection lifecycle.
 *
 * Pure: ChatPage owns the socket and state, this module owns the words and
 * the "which button goes with this failure" decision, so both can be tested
 * without xterm or a fake WebSocket. WebSocket close codes never appear in
 * user text — ChatPage logs them to the console instead.
