Tech-Tutorial YouTube-Thumbnail mit UI-Mockup

A clean, modern YouTube thumbnail on a solid bright white background, split visually between typography and interface on the left and a cropped presenter on the right. On the top left, a massive stacked headline in heavy black sans-serif uppercase reads "[CLAUDE DESIGN]" across two lines. Directly beneath it, a rounded rectangular orange banner with a subtle drop shadow contains bold white uppercase text reading "[IN 6 MINS]". Beside the headline is a small orange starburst spark, with another larger orange starburst in the far right background. In the lower-left area, a floating UI mockup of a design tool dashboard appears with a soft off-white panel, subtle shadow, and thin rounded borders; its left sidebar shows menu items "Recent", "Your designs", "Examples", and "Design systems", while the main panel shows a "Recent" header above three project cards labeled "Thumio Design System", "Thumio Startup", and "Design System". On the right, a cropped photorealistic young adult man in a white turtleneck sweater with messy light brown hair and light facial stubble points his index finger toward the dashboard mockup; a solid tan rectangle placeholder neatly covers his face. Crisp lighting, creator-economy aesthetic, warm orange and white brand palette, 16:9 composition.
