/* asset-pipeline-ASK_inheritance-spine.source.js
   Source data for the Inheritance diagram — Axis B.

   Renders WHERE information lives and how it inherits / overrides / combines:
   the layered IA as a normative hierarchy from the upstream-most brand-system
   layer down to the terminal slot. Conceptual basis:
   docs/layer-disambiguation-note-v1.md and docs/architecture.md.

   Rendered by the vertical spine engine (diagrams-spine-engine.js,
   window.DIAGRAMS.render). Axis B is a single-child inheritance chain, so it
   collapses into a straight centered top-to-bottom spine — the linear case the
   diagram-spine-static scaffold was designed for. The third layer varies by
   workflow mode; that variation lives in the node note so the chain stays
   linear (a branch there would fan the spine).

   STRUCTURAL map, not a maturity-state diagram: no `status` is asserted; the
   architectural nuance (brand-system unmodeled, category signaled-only, packet
   strongest carrier) rides in the notes, not in earned/held/legacy coloring.

   Illustrative, not source truth — repo prose (docs/architecture.md) is
   authoritative. Bump the source-v / render-v stamp in the HTML when topology
   or major content changes.
