/* Changed for Gould: v23's palette (spec decisions 6, 50, 58, 66 item 9).
   Four colours: navy (bg), mint (accent), pacific blue (blue), deep-space blue
   (primary). Neutrals don't count as colours: one white (#fafafa), pure black
   for shadows, and the framework's greys (white-dark, contrast scale) made
   pure grey at their old lightness, unused for now. No light/dark shade steps
   and no warning/success/error: the first spec that needs one adds it. HSL
   values round-trip to v23's hex exactly. */
