/* VendorPOSPro — tablet POS
   Design intent: outdoor-readable working tool. Light "griddle steel" ground,
   near-black ink, one hot accent (flat-top red). Kitchen-ticket vernacular:
   the order rail is a paper ticket; kitchen cards are tickets on a rail.
   System font stack on purpose — offline must never break typography. */
