/* ============================================================
   Брендбук · концепция 05 — «Гексагон»
   От базовой фигуры знака: шестиугольник = система и регламент.
   Соты программ вокруг узла расчёта, гексагональные маркеры,
   секция трёх контуров интегратора (модели · данные · правила).
   Строго по бренд-буку: Inter + Raleway, только синяя палитра
   (navy #19286d · гос-синий #0068b4 · cyan #00a6ca · стальной #296695).
