/* ==========================================================================
   GREENCOMO — Monolith design system
   Swiss industrial. Pure white, pure black, one signal vermilion.
   Grotesque at heavy weight and large scale; a hard rule frame; mono labels in
   a fixed left rail; square corners everywhere; no shadow, no gradient, no
   rounded corner anywhere in the sheet.

   The point of view: this is a machine plate, not a magazine. Rules are
   structural, not decorative. Type is the only ornament.

   One stylesheet for every page. Tokens live in :root only.
