/* ══════════════════════════════════════════════════════════════════════
   HIGH SIGNAL — editorial

   One system, applied everywhere. Cream ground, ink type, a serif for
   headlines and a sans for everything else, a fixed type scale and a
   fixed spacing scale. The logo green appears only on buttons and the
   smallest of details. No images except the founder video and the
   headshots; no icons except the outbound links on the speaker cards
   and under Salim's name.
