   Блок 1 — перенесён один в один из <style> боевой article.html
   (hero, прогресс-бар, TL;DR, оглавление, таблицы, callout'ы,
   FAQ, CTA, блок заявки .lb). Блок 2 — добавки для сгенерированного

   Оригинальные страницы article.html / article-dbs.html этот файл
   не используют — у них свой inline CSS.
