 * Icosmo Card Gallery - UI v1.1.0
 *
 * DESIGN RULES (shared with the DNA cards of Icosmo Helix):
 * - Full dark neutral design. Colour only comes from the cards and the Icosmo Matrix.
 * - Off state: dark background, dark border. Hover/Focus: white border.
 * - Base font, colours, panel frames and panel headings come from the shared Icosmo
 *   interface styles of Icosmo Matrix Core (icosmo-ui.css).
