/* THE HORSE BOUTIQUE - admin panel.
 *
 * The palette and type are the brand's: noir, graphite, steel, mist, paper,
 * white, and a light geometric sans with wide tracking on caps. The panel is
 * an internal tool, but it is the owner's own brand looking back at him, and a
 * tool that looks considered gets treated as trustworthy.
 *
 * Two signal colours exist and are used nowhere decorative - only where a
 * figure is wrong or money is being lost. A warning colour spent on ordinary
 * chrome stops meaning anything.
