When are things ever this simple?

Now is when. Activated, visited its page on the Dashboard menu, clicked two checkboxes, and the relevant products and categories were gated off. Even shows the correct alternate views and message so as not to disorient people who would otherwise see little or nothing.

Also, I totally get that Administrator is a role anyway, but it’s super easy to test with when you, as the admin, can just toggle yourself on and off to see how your changes affect things.
