<role> You are a senior UI designer who recreates pixel-accurate streaming interfaces for high-fidelity mockups and front-end prototypes. </role> <context> Build one static desktop view of a YouTube Premium live-stream watch page showing an interview/variety broadcast in progress. The on-screen wording is fixed and must appear verbatim: the sponsor ram mark reads "SARDI", the goal banner reads "TONIGHT'S GOAL: 0 to 25", and the bottom banner reads "K" followed by the streamer name. Five values change per project: - [search query] — default: bilal fraiha - [female guest] — default: Sydney Sweeney - [streamer name] — default: MOREBILAL - [video title] — default: FULL STREAM | سيدني سويني مع بلال - [channel name] — default: More Bilal No Filter </context> <task> Compose the page as three stacked regions, in this order: 1. Top navigation bar — "YouTube Premium" logo on the left, a rounded search field in the center containing [search query], and exactly 3 icons on the right. 2. Video player — [female guest] in a white cardigan and a bearded man in a beige jacket laughing, both seated on a couch, with two silver play-button plaques and a ram logo reading "SARDI" in the background. Layer three overlays over the video: a live chat column on the left with 15 messages using colored usernames and white message text; a goal banner in the top-right corner reading "TONIGHT'S GOAL: 0 to 25"; a bottom-center banner reading "K [streamer name]". Finish with a control bar containing exactly 10 controls. 3. Details panel — the title [video title], the channel [channel name], and exactly 5 action buttons beside or beneath them. </task> <constraints> - Honor every count exactly: 3 top-bar icons, 15 chat messages, 10 player controls, 5 detail buttons, 2 silver play buttons. - Reproduce all fixed wording verbatim; keep [video title] in its original Arabic script and right-to-left direction. - Apply YouTube's dark theme, a clean sans-serif typeface, and a consistent spacing rhythm. - Show only the elements listed above; add no extra sections, labels, or brand names. - Keep all text fully legible with nothing overlapping, clipped, or spilling outside its container. </constraints> <format> Deliver one self-contained layout description: a top-to-bottom arrangement of the three regions with precise placement notes and exact label text for every element. </format> <tone> Neutral product-design visual language: clean, minimal, balanced, legible. </tone> Now generate the complete livestream watch-page mockup following the specification above.
