/*
  Nhako home.

  Design language is carried over from nera.nhako.com (ButterflyOS): Silkscreen
  for chrome and labels, Nunito for prose, the pastel sky gradient, 1px --line
  rules and hard 3px offset shadows instead of soft ones.

  Two deliberate departures, because this page has a different job. Nera is a
  fullscreen OS: `overflow: hidden`, fixed panes, desktop-only. This one is a
  document, so it scrolls, reflows to a phone, and respects reduced motion.
