// safe protocol state. A queued-mode Close only drops the transport after the
// writer drains its outbox, so input already buffered in the connection can
// still be dispatched to the owner after the purge; a session left in the
// character menu with a nil account then dereferences sess.Account and kills
// the owner goroutine (and with it every session and all unsaved state).
