   Todi — app-todi.ru

   Цвета взяты из самого приложения (presentation/theme/Color.kt), а не
   придуманы заново: графитовый фон #0F1115, ирисовый акцент #8E9BFF,
   мягкий красный просрочки #F0A29B и «сделанный» зелёный #79D68C. Сайт
   должен читаться как продолжение приложения, поэтому палитра здесь одна
   на двоих, а не «примерно похожая».

   Шрифты свои и лежат рядом (assets/fonts): Manrope — заголовки,
   Inter — текст. В Google Fonts сайт не ходит: в России он часто
   недоступен, и внешний запрос на каждой загрузке — это ещё и лишняя
   утечка адреса посетителя на чужой сервер.
