+/// <summary>
+///     Renames the "Staff" system customer group to "Store manager", matching the earlier rename of
+///     <see cref="SystemCustomerGroupNames.StoreManager" /> (previously <c>Staff</c>). Installations that
+///     existed before that rename still have a <see cref="CustomerGroup" /> document with
+///     SystemName "Staff", seeded by the old installer. Code now looks up the store-manager group by
+///     <see cref="SystemCustomerGroupNames.StoreManager" />, so an un-migrated installation silently loses
+///     that group. This brings the existing document's SystemName (and, if untouched by an operator, its
+///     display Name) in line with the current naming.
