Source video asset(s) used by the Docker build to bake the rickroll video into the image (build-time fetch, not stored in git history/LFS).
- video4k.mkv - primary master (4K). All resolution tags (1080p, 720p, etc.) are derived from this via the Dockerfile's RESOLUTION build arg.
- video.mp4 - legacy 1080p interim asset, kept for reference.
