Supplier country options available for filtering in the drawer search panel. Derived from COUNTRIES (already sorted alphabetically by name).
ISO 3166-1 alpha-2 codes of the 27 EU member states. country-list-js exposes

Supported countries for location-based features such as currency and shipping filters. Sourced from
