/* SalexFyPOS marketing site
   Design concept: the counter, not the cloud.
   Paper-white sections (the till receipt) alternate with a dark
   register-panel section (the amber VFD display of an old cash
   register). Mono type carries prices and data, exactly as it
   would on a real receipt; a grotesk display face carries voice. */
