- Use object-fit: cover and keep the focal motion visible on desktop and mobile.
- Add a readable overlay only when foreground text needs contrast.
- Keep controls hidden for decorative background use, and provide a poster/thumbnail fallback.
- Respect the MotionSites authorization state before using this asset in a commercial project.
