/* GHAUS — depth
   The page is a descent. The background runs from the lit water at the top
   to the abyss at the bottom of the document, and a gauge on the right reads
   the scroll position in metres. One warm accent (pearl) for anything that
   claims exclusivity; one cold accent (aqua) for instruments and readouts.
   Nothing glows, nothing is pure black or pure white. Prose in a humanist
   sans at 17px; the serif carries the voice; mono carries numbers. */
