   GUIDE LONGREAD — редакционный стиль для статей раздела «Гид».
   Отдельная система, НЕ переиспользует компоненты инструментов:
   узкая колонка для чтения, крупная типографика, врезки «Ключевое»
   в конце каждого раздела (как у референса), FAQ.
   Токены (--teal, --navy, --gold, --text…) — глобальные из _bundle.css.
