 1// Package genesis is the thin adapter that registers the genesis engine
 2// (p/…/art/art/genesis/v1) with core. It dogfoods the third-party path: core
 3// knows genesis only as this realm's package path plus an interface value.
 4//
 5// The adapter is stateless and has no admin: what it renders is fixed by
 6// the p/ package it imports, which can never change. Never mark this realm
 7// private (design §5.4: a re-deployable adapter could swap the art).
