/* Acante — сайт продаж, по презентации acante-prezentaciya.pptx
   (палитра/структура/тексты владелец выверял сам, дословно). Никаких
   фотографий — только цвет, форма (круги — сквозной мотив) и
   типографика: засечная Playfair Display в заголовках, Inter в тексте
   — контраст между ними и есть половина стиля (слова владельца). */
