## Problem

The logistics team noticed orders shipping to broad regions (orders.region, e.g. 'EU', 'APAC') that don't line up with any country we have on file for customers (customers.country). Count the number of distinct order regions that do NOT appear as any customer's country. Return a single number as cross_region_count.
