 * Direction: a field-guide for people who want to slow down. Deep moss green
 * as the one brand colour, warm paper neutrals, one amber accent kept for
 * large type on the dark band. Dark mode is a night forest, not an inversion:
 * the ground goes near-black green and the accent lifts to a pale sage.
 *
 * PALETTE (3-5 colours): moss green, paper, forest ink, sage, amber.
