/* ---------------------------------------------------------------------------
   Barya site tokens.

   Lifted from the app's src/constants/theme.ts rather than invented for the
   web, so the page and the app are the same object. Two grounds, pure black
   and pure white. Structure is 1px hairlines and nothing else: no fills, no
   shadows, no accent colour, no radii. An editorial serif carries every
   number a person reads as money; the platform grotesque carries every label.

   Shared by /barya/, /barya/support/ and /barya/privacy/ so the three pages
   are one stylesheet and one download.
