   TOKENS

   The book is about the difference between marks that wipe away
   and marks that are cut in. That contrast is the design: dense,
   saturated marks on a clean surface, nothing muddy between.

   Jade is oxidised copper, the colour of an engraving plate.
   Amber appears only where a reader has made progress or done
   something. It is never decoration.
