How do I create a scratch org that has the same namespace as my Developer Edition org where the managed package is held?
I've followed the instructions in the "Link a Namespace to a Dev Hub Org" page to link the namespace to my Dev Hub org, but I cannot find any instructions on any of the documentation pages below for how to actually create a new scratch org that has the same namespace as my DE org.

In the project configuration file, specify the namespace.
This really only alluded to in the documentation, but
sfdx-project.json
is the key to creating a scratch org with a namespace.
