/* GlazeTag public site. One stylesheet, no scripts, no webfonts, nothing third
   party. A privacy page that fetches a font from another company in order to
   say it collects nothing is a page that hands the reader's address to that
   company. So: system fonts only, everything served from Pages.

   The visual idea is a specimen archive. Porcelain paper, charcoal text,
   cobalt for anything actionable, oxidised copper used sparingly. Tile codes
   are set like the label on a museum specimen card: mono, letterspaced, above
   a hairline rule. */
