/* Defra architecture - theme for MkDocs Material.
 *
 * Palette follows the Defra strategic architecture prototypes: deep navy for
 * structure, Defra green for anything that carries meaning or text, and lime
 * used sparingly as a highlight on dark backgrounds only (it fails contrast
 * on white). Every text colour meets WCAG 2.2 AA on its background.
