/*
 * Supplementary styles for CCA UI Profile v2.
 *
 * GOV.UK Frontend 6.4.0 supplies the shell, grid, typography, and components.
 * This file adds only what the design system does not provide: the metric
 * tiles, the capacity utilisation bar, the result list, and the CCA brand mark.
 *
 * Every colour is a GOV.UK palette token, per CCA-UI-001:
 *   #1d70b8 blue     #003078 dark blue   #00703c green
 *   #d4351c red      #f47738 orange      #ffdd00 yellow
 *   #0b0c0c black    #505a5f dark grey   #b1b4b6 mid grey   #f3f2f1 light grey
 *
 * Responsive boundaries match the fleet's 640/641/768 breakpoints.
