   Брендбук · концепция 04 — «Схема линий»
   Услуги как маршрутная карта в традиции схем метро:
   три линии — три аудитории, станции — программы,
   пересадочный узел — личный кабинет.
   Цвета линий = дополнительные цвета бренд-бука:
   Л1 гос-синий #0068b4 · Л2 стальной #296695 · Л3 cyan #00a6ca.
   Основа: navy #19286d, Inter + Raleway.
