/*
 * DermaMedica admin area.
 *
 * This file deliberately defines NO colours, fonts, radii or shadows of its own.
 * Every value below resolves to a custom property declared in dermamedica.css -
 * --navy, --sand, --font-display, --radius-md and so on - which the admin
 * layouts load first.
 *
 * That is the whole point: the admin panel is the same product as the public
 * site, so when the brand palette or the type scale changes there, the admin
 * follows without anyone having to remember this file exists. Hard-coding a hex
 * value here would create exactly the drift we are avoiding.
 *
 * Class names keep the `adm-` prefix carried over from CandleCraft.
 *
 * Layout is fluid from 320px up - Charlotte checks this on an iPad (US 5.1).
