/* ==========================================================================
   Verdanta International — design system
   Concept: a trader's desk at dusk. Deep indigo canvas (the historic colour
   of India's own dye export trade) holds paper-toned "document" cards —
   manifests, certificates, ledgers — the working material of an export
   house. Turmeric marks what you can act on; stamp-red marks what has been
   verified; cardamom marks what is fresh. Mono type reads like a typed
   manifest, serif type reads like a printed ledger page.
