Create a cinematic 16:9 brand-neutral livestream platform interface showing [Pianist] performing [Event] on [Platform Name]. Use the look of a premium classical concert broadcast: a grand concert hall with warm golden stage lighting, a black grand piano, an audience in the background, and the pianist seated at the keyboard in formal concert attire. Compose the image as a realistic desktop streaming page with a large main video player on the left, a red LIVE badge, a search bar with the recital title, a right-side live chat panel, viewer statistics, reaction icons, share/save controls, a channel row, and a short video description below. Keep all UI labels fictional and generic, with readable but not brand-copying text. Avoid real platform logos, copied piano-maker logos, celebrity likenesses, official channel claims, private user data, extra watermarks, distorted hands, impossible piano keys, unreadable chat text, broken interface spacing, and low-resolution artifacts.
