Make a 20-second launch film for a fictional product, made entirely in code. No video models, no image generation, no stock footage. The product: Halo, wireless earbuds that glow softly when music plays. Keynote style: a dark stage, the earbud case opens and an earbud floats out and turns in the light, light trails sweep around it, three short taglines, a price reveal ($149), and it ends on the Halo logo. Make it feel like a real product launch, not a slideshow. 1920x1080, 30 fps, with sound made in code (a music bed or sound design) if you can. Deliver the rendered MP4 (keep it under 50 MB) and the source.
