// Package layoutvalidationviewv1 defines the pure, content-addressed Catalog
// projection used to validate layout-bundle references against one exact
// Catalog snapshot.
//
// The package owns value validation, canonicalization, digest construction,
// and typed verification of the two referenced neutral artifacts. It
// deliberately owns no registry, persistence, publication selector, serving
// path, source-bound artifact loader, or authority-proof artifact. A caller
// must load the exact canonical referenced bytes and verify every authority
// evidence digest with the registry that owns that evidence before admitting a
// view.
