/**
 * Amaru (conduit) /thesis — TH1→TH8 lineage ribbon surface.
 *
 * Amaru is the Andean ouroboros artifact; it hosts the only first-class
 * TH1→TH8 lineage ribbon. The other six shipped artifacts surface the
 * lineage as a single panel inside their GovernancePanels; this page is the
 * canonical render.
