        "elegantly pans from shoes to face. Dramatic runway lighting, crisp highlights, "
        "and an upbeat, trendy soundtrack add excitement. In the final second, the "
        "model stops, looks directly into the camera with a smile, and the scene "
        "blurs to a bold, minimalist animated brand title card: 'Best Name.' The "
        "whole scene is energetic, clean, visually striking, and lasts 8 seconds, "
        "echoing top luxury fashion campaigns."
