/* ==========================================================================
   Bayarcash PHP Demo — design system

   Warm paper, deep pine, editorial type. No gradients, no glow, no grain:
   the craft is in spacing, hierarchy and rhythm, so it still reads well
   in five years. Colour is reserved for payment state, where it means
   something.

   Built mobile-first. Every layout rule starts single-column.
