 * СОЗ «Тайга» — стили сайта.

 * Основа перенесена с оригинального одностраничника taiga.su без изменений:
 * палитра, типографика, карточки, hover-эффекты и анимации. Ниже, в блоке
 * «Многостраничность», добавлено только то, чего на одностраничнике не было:
 * стили внутренних страниц, хлебных крошек и формы обратной связи.
 *
 * Bootstrap 5 подключается ДО этого файла и отвечает за сетку, аккордеон
 * и формы — визуальную идентичность задаёт этот файл.
