   =============================================================================

   No webfont, by design. The page copy states that it loads nothing from
   anyone else's server, and a Google Fonts <link> would make that false — it
   discloses the visitor's IP and User-Agent to a third party on every view,
   which is exactly the claim being made about the products.

   So: system faces only. A serif for display, the platform UI sans for text,
   and a mono for the small data-ish labels.
