   Palette: near-black slate + electric blue accent.
   Signature element: the "ticket" card (dashed edge,
   monospace figures) echoing a real receipt chit.
   NOTE: the --gold variable name is kept for backwards
   compatibility with .btn-gold / accent classes below —
   its value is now a tech blue, not literal gold.
