/*
  /preview/crypto/ campaign layer (Binary Systems, Inc.): "Cryptocurrency".
  Same family as /Company/ and /Clients/ (co- classes), loaded AFTER the five live stylesheets.
  Always dark ("vault" look) regardless of colour scheme. Body type stays the live
  "Lucida Grande" stack from text.css; only hashes and code use a monospace stack.
  Accents: Monero orange is the page accent; Bitcoin orange and Ethereum blue-violet
  appear only inside their chain cards.
