/* =========================================================================
   Layout — Corporate
   Personality: consultancy / annual report.
   Restrained, institutional, document-feeling. IBM Plex Sans/Mono pair.
   Left-aligned hero with vertical "Annual Report · YYYY · Vol. I" rail.
   Cards are document blocks with a doubled top rule (thick + hairline),
   tracked uppercase eyebrow, and a Roman numeral that becomes a quiet
   bottom-right page marker. Metrics are bordered cells on a neutral paper
   background with mono labels — like a financial summary table.
   Scoped via body.layout-corporate so no other layouts are affected.
