 * Brief: an internal print-shop tool for an automation agency. Dense and calm

 * from printers' registration marks. Space Grotesk for headings and figures,
 * Manrope for reading, JetBrains Mono for short links and codes.
 *
 * Opens light. Dark is a separate palette (graphite ground, a lighter orange
 * with dark ink on it), not the light one inverted.
