   Identity: the Field. Monochrome — ink, paper, two metals. No accent colour.
   Type: Archivo (wide capitals for the wordmark, normal width for text),
   JetBrains Mono for every label, code and index.
   The dot field is the ground of every page; the mark is the field with
   some points enlarged.
