/* Unlimited Civil brand base for the public pages: Home, Sign in, Back Office sign in.
   Source: the marketing "Unlimited Civil Marketing System" canvas, 01 Identity.

   ADR-0095 roles): they are always the brand's Paper look (white ground, slate text, blue accent).
   "Derived" values are not on the Identity page; they are the brand page's own supporting colors
   or were derived to meet WCAG 2.2 AA, as noted. */
