requires shipping

Whether the product is physical and must be shipped, or digital and needs no shipping — the structural fork into the digital-delivery concern. Feeds checkout's address-collection decision. Cardinality one. A governed token (requires-shipping / digital-no-shipping). A positive declaration, not derivable from an empty fulfilment_channel set (the b75 identifier_exists precedent) nor from kind alone (a gift card is physical OR digital). The digital-delivery concern builds on this fork (its forms qualify the digital branch).

Requires shipping is answered with one word chosen from the shipping requirement list — the same word shared across every product that uses it.

It belongs to fulfilment — one facet of a product.
