/// How fast each locomotion clip actually carries the zombie, in units/sec,

/// ⚠️ THIS is a zombie's movement speed - not the round curve. The original
/// derives speed from the playing animation (GetSequenceGroundSpeed, moo:454)
/// and uses the round number only to pick which tier of animation to play
/// (nz_zombie_walker_derriese:772 + its Threshold table). That is why a round-1
/// zombie still shambles forward at ~46 u/s even though its curve value is 0.

/// s&box has no ground-speed accessor - SkinnedModelRenderer.SequenceAccessor
/// exposes Duration/Time/PlaybackRate and nothing about root motion - so the
