   QUINTALUZ  |  V4, the descent
   Near-black. One hue at a time. Long passages of darkness between
   moments. Inscriptions, not paragraphs. An artwork first, a website
   reluctantly.
   Type: Space Grotesk (self-hosted, variable weight).
   Three sizes only: display, small-caps label, fine print.
