Piece Specifications
-- used as default values for any record missing dimensions in your CSV
These dimensions are sent to the engine as piece_defaults -- they apply to every record where WIDTH / HEIGHT / THICKNESS / WEIGHT is absent or zero in the CSV.
When auto-versioning is on, the engine also uses these as the fallback for any version not otherwise specified.
