/* =====================================================================
   BOLD PIZZERIA — design system
   Direction: "char and brass." The room is dark walnut and blackened steel;
   the only warmth is fire. Brass is the house metal. Ember is reserved
   exclusively for one job — telling you something is running late.
   Signature: the heat scale. Every ticket, run and station carries a bar
   whose fill and colour are driven by elapsed time against its target, so
   lateness is a material on screen, not a badge.
