/*
  Main colour: iron blue #245E78, chosen for Ferroguard.
  Accent: that hue plus 137.5 degrees, at the same saturation and lightness.
  Support: the same hue and lightness, with 40% of the main saturation.
  The golden angle is about 137.5 degrees. It is not a contrast ratio.
  Links, buttons, and focus use the tokens below, checked on their own backgrounds.
  Page surfaces stay neutral. The three derived colours do not share the page.
