  Grace Assembly of God brand, sampled from graceag.sg (the same palette as go.graceag.sg):
  slate text #334155, headings #1e293b, the red of the round logo #CF2127 as the accent,
  light grey panels, the system font stack. Dark mode is our own: the same slate family, with the
  red lightened so it stays readable on dark (5.6:1).
