a static screen recording of a Russian-language website, likely a book or story platform, showing a page for a work titled "Кайн" (Kain) with a cover art depicting a figure in a dark landscape. The screen then scrolls down to reveal the beginning of the story's text, which is titled "Вступление" (Introduction), and a comment section with a user profile picture and a "Следующий пост" (Next post) button.
