/* Hopzup design tokens — "Hop" direction (design_handoff_hopzup/tokens).
   The --hz-* tokens are the design's own names and values. The older names
   further down (--surface, --ink, --brand …) are aliases onto them, so every
   existing component follows the new palette, light and dark, until it is
   rebuilt. Nothing else in the stylesheets should hard-code a colour.

   Fonts are self-hosted subsets from @fontsource (SIL OFL 1.1): Outfit for
   Latin, Noto Sans for Cyrillic (Outfit has none), Noto Sans Arabic and
   IBM Plex Mono for codes and labels. */
