   КОЛОКОЛЬЧИК — личные уведомления в шапке
   theme/dist-tutor/css/notices.css

   Живёт в .dt-nav-actions рядом с выбором города, облик — «Класса»:
   кнопка-пилюля, панель-стекло, акцент #0a84ff.

   Ловушки портала (AGENTS.md): 1rem = 10px, глобальное * { margin: 0 auto },
   бутстраповский .hide прячет элемент — поэтому у .dt-bell__badge нельзя
   задавать display в базовом правиле.
