   kb.css — единая дизайн-система «база знаний + интеграции» свóдно.
   Один визуальный язык с /integrations/t-bank/ (эталон): те же токены
   mint(--primary) / amber(--accent) / night(--night), Manrope + JetBrains Mono.

   Подключается на: help_article (single/archive/tax) + /integrations (хаб).
   Все токены берутся из assets/style.css :root — здесь ничего не переопределяем,
   только компоненты. Всё скоупится под .kb, чтобы не течь в глобальную тему.
