Which half of the band a violin occupies: both (full symmetric violin, default), lt (left when vertical / top when horizontal), rb (right / bottom), or split (auto-assign the two halves from a 2-level color/segregate group, seaborn split=True). May be given as a single value (applies to all groups) or as an object keyed by variable name or sample-group name for per-variable / per-sample sides, e.g. {"Before":"lt","After":"rb"}
