/* ============================================================
   YURCONSULT — landing 5.1 (contrast minimal, open)
   Чистый чёрно-белый: плоские поверхности, прямые углы,
   контурная графика, инверсия при наведении.
   Структура 5.1: сетки «раскрыты» — вместо коробок с рамками
   отдельные ячейки на воздухе + волосяные линии; открытые
   ведомости, бегущая строка доменов, рейл-индикатор секции,
   прогресс скролла, гигантский контурный вордмарк в футере.
   ============================================================ */
