     --font-display is the Latin display face used for section labels and the
     global nav. Copperplate is the face the design specifies: it ships with
     macOS and iOS, and on Windows it usually arrives with Office. Anything
     without it falls back to the platform serif, which keeps the same
     high-contrast, capitals-first feel.
