Прежняя анимация растягивала полоску через несколько строк и тянула подсветку поверх текста — это выглядело как сбой отрисовки. Теперь по левому краю едет короткая акцентная капсула: в полёте она чуть вытягивается, за ней тает хвост, вокруг мягкое свечение. Подсветка старой строки плавно гаснет, а новая строка закрашивается слева направо под текстом. На новой строке капсула коротко пружинит и становится обычной полоской (в списке пресетов, где своей полоски нет, тает), значок строки подпрыгивает.
