Packages

A package is a saved box: a name and its outer dimensions. Define the ones you actually pack into, and your team picks a package by name instead of typing dimensions on every shipment: fewer keystrokes, and far fewer re-rates caused by a mistyped size.

Packages carry dimensions only, not weight. Weight varies with what goes in the box, so it stays on the parcel.

One package on the account can be the default (is_default), which is the one pre-selected when a shipment is created in the dashboard. Setting a new default clears the old one, because only one is allowed. The default can be replaced but never removed, so an account that has one always has one.
