유튜브 아웃트로

Square presentation mockup of a polished YouTube outro design displayed on a widescreen monitor. The landscape end screen features two balanced video-thumbnail placeholders, a central circular channel-avatar space, a slim progress accent, and a clean subscribe-button shape, arranged on a deep navy-to-violet gradient with subtle geometric motion trails. Include a compact editing timeline at the bottom edge to suggest video production. Cinematic ambient desk lighting, straight-on view, precise spacing, no brand logo, no readable text, no watermark.
