Media union for Product.media: a captive Image or Video reference.
Both variants share the reference storage class but carry disjoint IRI patterns, so a stored reference
singles out its branch by target-identifier pattern (§5.4). Both are captive, so they are cascade-deleted
with the owning Product.
