    # Bounds the method by the packed volume of the shipment, in cubic
    # meters. This is what turns a wholesale tier table into configuration: a
    # "Pallet" method takes 1–15 CBM, a "20ft container" 15–33, and the
    # estimator offers whichever one the order actually fills.
    #
    # Unlike {WeightRule}, the compared value is always converted to CBM
    # first. Dimensions are stored in whatever unit the merchant typed, and
    # inches read as centimeters overstate a carton roughly sixteenfold — too
    # large an error to leave to convention.
