   Акцентный шрифт по ТЗ — Celestina (рукописный/скриптовый шрифт студии
   Piñata Foundry). У Celestina нет открытой лицензии для встраивания как
   веб-шрифта на коммерческом сайте (бесплатна только для личного
   использования, для бизнеса нужна платная лицензия на MyFonts). Чтобы
   не нарушать лицензию, по умолчанию используется ближайший по духу
   бесплатный шрифт с открытой лицензией — Caveat (Google Fonts),
   рукописный, с похожим "бодрым" почерком. Если у вас есть купленный
   файл Celestina — просто положите его в assets/fonts/ и раскомментируйте
   @font-face ниже, тогда сайт будет использовать настоящую Celestina.
