   GEMMA COFFEE × ИДЕЯ — коммерческое предложение
   Редакционная система: белый фон, чёрный текст, синий #202EB0.
   Дисплей — Prata (кириллическая антиква), текст и данные — Manrope.
   Правила: одна фокусная точка на сцену, волосяные линейки вместо
   коробок, сцена всегда помещается в экран (JS-фитектор).
