/* ==========================================================================
   Кастомные стили объединённого шаблона cassiopeia_ptbstyle.
   Собраны из трёх бывших шаблонов:
     cassiopeia_ptbstyle    -> главная страница   (класс .ptb-home на <html>)
     cassiopeia_ptbmaterial -> материалы          (класс .ptb-material на <html>)
     cassiopeia_catalog     -> каталог курсов     (класс .ptb-catalog на <html>)
   Общие для всех страниц правила записаны как есть. Правила, которые были
   только в одном/двух шаблонах, обёрнуты в :where(.ptb-...) — :where() не
   добавляет специфичности, поэтому стили работают ровно как раньше.
   Порядок правил сохранён для каждой страницы.
