/* Palette is built around the sage #d3e0dc: it is the border and tint colour,
   the page sits on a paler wash of it, and the accent is the same hue taken
   dark enough to stay readable on white. Severity colours are shifted toward
   the same muted register so nothing shouts louder than its severity. */
