/* «Сообщения» внутри лаборатории (ADR-0053) — общий модуль программы (раздел
   «Сообщения») и приложения техника (вкладка «Сообщения»). Классы zc-*: общий
   слой app.css их не перекрывает. Широко — две панели (список 380 и чат), узко и
   в приложении — экраны стопкой: список, чат и сведения выезжают справа и уходят
   свайпом вправо (lab-chat.js). Цвета — только токены theme.css. */
