   FOREPINE — shared design system (v4)
   Monochrome, taken from the logo: ink on paper, with a warm
   off-white for tinted bands. Outfit carries every heading and
   paragraph; JetBrains Mono is only for small labels (eyebrows,
   numbers, statuses). The swept bands in the hero panel are the
   one loud moment; everything else moves briefly and quietly.
