   literals live in :root and nowhere else; mono is set ONLY on the register

   one family: serif = headings and the one hero sentence, sans = every
   sentence, mono = a value, a unit, a date and the fixed lines. The fallback
   stack is part of the design: the page reads fully before a font arrives. */
