Пожалуйста, сформируй полный HTML-код (ничего не пропускай), выделив его обратными тройными кавычками, для следующего запроса: "1) Полоса прокрутки в блоке с текстом должна быть стилизована в стиле цветовой схемы приложения. 2) Картинка на заднем фоне должна быть с затемнением. Если для этого требуется перестройка структуры, то нужны создать блок, поместить на фон картинку, через after затемнить, а остальной контент второй секции поместить в другой контейнер на том же уровне и задать ему z-index больше, чтобы он перекрывал блок с картинкой". В прошлой итерации код выглядел следующим образом: "<!DOCTYPE html>
