   Lex on Tech — lexontech.org

   All-sans, high-contrast, editorial. Avenir Next where the
   reader has it (most Apple hardware does); Mulish, a close
   humanist-geometric match, everywhere else.

   The rules of this design: emphasis comes from weight, size,
   and rules — never from italics. One accent colour, used
   decisively and sparingly. Square corners over soft ones.
