/* CrestStone · "Stone doesn't bend. Clay does."
   Oxide: a white page and near-black type, so the real stone, marble and earth in the photographs carry all the colour.
   Fired clay appears twice, as bookends: the opening, and Talk to us with the footer. No cream, no black chassis.
   Instrument Serif (roman only) for titles, Jost for everything else. Sentence case everywhere, no tracked capitals.
   Type for an older audience: running text 20 to 22px, nothing under 16px, 56px buttons. */
