/* Donmotor — дизайн-система «Культурный архив», вариант «Техническая документация».
   Полиграфическая типографика, деликатные линейки, спокойный цвет; характерные элементы — хронологии и подписи к источникам.
   Отличия от moscowdronefestival.ru (сепия, масттед по центру) и latarta.ru (каталог коллекции, ягодный акцент):
   шапка — штамп чертежа с ячейками и номером листа, нумерация разделов «01, 02…», чертёжная бумага, оксидно-красный акцент. */
