Create a vertical 9:16 fictional social media profile page for King Taejo Yi Seong-gye shortly before the Wihwa Island Retreat. Use a dark-mode microblog interface inspired by modern social platforms, but keep it generic and brand-neutral. Include a historical military header image, profile portrait, verified-style badge, follower count, tabs, and several Korean-language posts where Yi Seong-gye and General Choi Yeong exchange sharp political and military criticisms. Make the layout feel like a historical parody document, with readable Korean post blocks, reply/repost/like/view icons, and a serious late-Goryeo atmosphere. Avoid real platform logos, trademarked UI, modern political endorsements, defamatory real-person claims, inaccurate hate content, unreadable critical text, and low-resolution artifacts.
