/* ============================================================================
   ds.css — the design system: tokens and primitives.

   Swiss / brutalist, derived from the `Lines and Planes v2` prototype. That
   prototype carried its styling entirely in inline attributes and had no
   stylesheet to vendor, so this file reconstructs the system it implied:

     · one typeface, Archivo, doing every job through weight and tracking
     · pure white ground, near-black ink, and a single red
     · hard 1px and 2px rules; no radius anywhere, and no shadows
     · headings set uppercase, tight and heavy; labels uppercase, wide and small
     · structure drawn with borders that meet at square corners

   Retune the look here. Everything above this layer — theme.css for dark mode,
   site.css for layout — reads from these variables.
