/* Juspit brand foundation — shared tokens and application shell.
   The brand book palette is achromatic and has exactly three values:
   #F3F3F3 (light), #000000 (black), #3C3C3B (warm dark gray). Production adds
   restrained semantic state colours and one approved chromatic exception for
   Host performance and bonus chart marks only. */

/* The brand typeface is Helvetica Neue LT Com Extended, which we have no
   webfont licence for. Archivo (SIL OFL) is the substitute: it carries a real
   width axis, so the display voice can stay extended while UI text stays at
   normal width. See --stretch-display / --stretch-ui below. */
