Create a vertical 9:16 screenshot-style image of a generic short-video livestream interface. Show [Host Name], an authorized or fictional adult livestream host, broadcasting from a warm indoor studio with soft lamp light, flowers, shelves, and a friendly intimate atmosphere. The host should face the camera and hold a pastel sign board that clearly says: [Sign Text].
Design the image like a polished mobile livestream screen: a fictional username and follower count near the top, a live badge, small viewer avatars, floating hearts on the side, gift icons, chat message bubbles at the bottom, and a comment input bar. Keep the UI realistic, layered, and readable without copying any real platform. Use flattering soft commercial lighting, natural skin texture, elegant styling, and a welcoming expression. Avoid real platform logos, Douyin or TikTok branding, real celebrity likenesses, real person names, private information, ChatGPT interface, browser chrome, app chrome outside the livestream, extra watermarks, unreadable sign text, malformed chat overlays, distorted hands, and low-resolution artifacts.
