/* ===== OkaK design tokens =====
   Тёмный фон, стеклянные панели, один тёплый акцент (коралл) для действий/ссылок
   и классический имиджборд-зелёный только для гринтекста (это функциональная
   конвенция жанра, её стоит сохранить). Моно-шрифт для ID/времени — это
   "техническая" метадата постов, как в терминале/девтулзах браузера.
