   Монограмма RVX белым, поверх тёмного фона, маской погашена к краям —
   не плашка, а свечение. Знак широкий и низкий, поэтому размер задаётся по
   ширине. На внутренних страницах шапка пустая — знак стоит справа. На главной
   справа карточка «How a quote happens», поэтому знак растянут по центру: крылья
   уходят под текст и под карточку, а звезда приходится на свободное поле.
