   Art direction: a furniture workshop catalogue, set like a technical document.
   Paper and ink do the work; hairline rules are the grid made visible; the only
   colour that carries meaning is walnut (heat, wood, the PUR glue line).

   Two self-hosted OFL faces, 51 KB together, preloaded (see head.jet):
   Instrument Serif for display, Instrument Sans for everything else.

   Budget: this file must stay under 35 KB gzipped.
