A dependency-free Python script (standard library only) that asks a few guided questions — do you have the pristine original, what is the job, what content, what viewing device — and prints the metric or panel to use plus the exact FFmpeg/libvmaf command to compute it. Runs interactively or fully from flags for CI use; includes a --demo. This is cross-cutting asset B2, the companion to article 2.11. (ZIP containing 1 file(s) — scripts, datasets, provenance).
