/* === FIX: положение плашки "печатает" у сообщений героя ===
   Проблема была в том, что у .chat-row--you блок .message растягивался
   на всю левую колонку сетки, поэтому короткая плашка "печатает"
   визуально уезжала далеко от аватарки "Ты".

   Эти правила прижимают сообщение героя к правому краю своей колонки,
   то есть ближе к аватарке. Работает и для обычных сообщений героя,
   и для короткой typing-плашки.
