   Qollqa Register — visual identity: THE INSTRUMENT.
   Cool paper, dark masthead, sans figures, mono metadata. Deliberately
   unlike machineaccountabilitycorp.com, which is the publisher's page
   and wears an editorial serif. A reader should never mistake the
   record for the corporation that keeps it.
