/* ==========================================================================
   Englishteacher — Святослав, преподаватель английского языка

   Визуальная концепция: editorial personal brand.
   Тёплый молочный фон + графитово-чёрные акцентные секции + один
   выразительный акцент (обожжённый оранжево-красный) — используется
   осмысленно: CTA, номера секций, отметки, hover. Крупная контрастная
   типографика (Fraunces display + Inter текст + JetBrains Mono лейблы
   и номера) работает как в журнальной вёрстке: большие заголовки,
   мелкие технические подписи, воздух.

   Mobile-first stylesheet.
