properties /availability

property token a chosen word

ineligible region

A region in which the offer is NOT valid / the product may not be bought (an explicit exclusion, e.g. shopping-ads-excluded countries). Token from the Regions vocabulary (countries and supranational blocs); cardinality many. The complement-facing twin of eligible_region; an offer may state either or both. The realised exclusion list is offer-level downstream; the grammar is universal.

Ineligible region is answered with one word chosen from the regions list — the same word shared across every product that uses it.

It belongs to availability — whether it can be obtained.
