   Concept: the visual language of audit ledgers and governance
   maturity scales — deep ink, ledger-line green, a brass/oxblood
   assurance-seal accent. The recurring signature motif is the
   Governance Maturity Scale (Level 0 → Level 4), used as a real
   structural device since IGMA's methodology is genuinely level-based.
