   Self-hosted, issue #16. The pages used to pull IBM Plex from
   fonts.googleapis.com / fonts.gstatic.com, which sent every visitor's IP to
   Google from four hosts - including booking.nexusnode.ru, the host this demo
   presents as "no tag, no cookie, nothing of Google's". A demo that sells a
   clean partner host cannot make a third-party request from it.

   Files are the exact latin and latin-ext woff2 subsets Google serves for
   IBM Plex Sans (400/500/600, one variable file per subset) and IBM Plex Mono
   (400/500). IBM Plex is SIL OFL 1.1; the licence travels with them in
   /shared/fonts/LICENSE.txt. Unicode ranges are copied from Google's own CSS,
   so a character outside them falls back exactly as it did before.
   font-display: swap keeps the old `&display=swap` behaviour. */
