// v0.38 Schema Pack primitives — the five composable defaults.
//
// A primitive is a named bundle of (default link verbs, default frontmatter
// fields, expert-routing flag, enrichment rubric slot). Pack types extend
// one primitive by name; the primitive's defaults flow through unless the
// type overrides specific fields. Closed enum — packs CANNOT add new
// primitives, only types that extend them. This keeps compile-time
// exhaustiveness available on the primitive enum even though PageType
// is now open string.
//
// Primitives drive INHERITANCE DEFAULTS only — NOT query closure. The E8
// refinement of D12 separates these two axe
