   Tech Knows You — the blog · design system
   --------------------------------------------------------------------------
   A small, sharply set publication about online advertising. Warm paper,
   ink, one electric ultramarine, one highlighter yellow. Fraunces carries
   display + prose; Space Grotesk carries the chrome; the data wears mono.
   The landing page's ad grid ("the Exhibit") is framed like a museum vitrine:
   hairlines, labels, provenance card. Everything else is ad-free reading.
