 * Design tokens — the PADUM design system (padum_booking/css/tokens.css),

 * palette: navy #244D78, coral #D2564E, sun #FAC669.
 *
 * Colour roles, kept from the source so the meaning travels with the hue:
 *   brand   navigation, headings, primary buttons
 *   accent  the CI yellow — a FILL with dark text only, never white text
 *   danger  coral: a person has to do something (destructive, blocking)
 *   success "done and needs nothing from you"
