/* Registry Ledger — design system for the re-scoped business.
   Deliberately unlike the parent build's Codex (white paper / serif / margin notes):
   this is a working ledger — slate ink on pale grey-green, double-ruled tables,
   tabular mono for every datum, stamps rendered as ruled boxes, no cards, no gradients. */
