/* ==========================================================================
   СОСТОЯНИЯ КНОПОК

   Раньше подсветка держалась на одном лишь :hover. На сенсорных экранах
   он «залипает» после тапа (и снимается только тапом в другом месте),
   а после клика мышью на кнопке остаётся фокус — свечение выглядело
   застрявшим. Теперь:
     :active        — свечение ровно на время нажатия;
     :hover         — только там, где есть настоящий курсор (см. media выше);
     :focus-visible — рамка только при навигации с клавиатуры.
