   СТИЛИ ПРОЕКТА «АВТОМАЛЯР АЛЕКСЕЙ» (ПО СТАНДАРТУ VERSTORIA-SG v2.10)
   Концепция: «Глянец и хром» — премиальная тёмная тема с холодным
   сине-неоновым акцентом, стеклянными панелями и металлической типографикой.
   Дизайнерские приёмы: редакционный hero с контурным текстом, наклонная
   лента услуг, журнальная сетка преимуществ, таймлайн этапов,
   полноэкранное мобильное меню и диалоги с градиентным кантом.
   Методология: БЭМ, адаптивность и чистая сетка
