/* Self-hosted so the card reads the same everywhere, offline-friendly and
   with no request to a third party. PT Serif/PT Sans are one family drawn
   together for Cyrillic, which is why Russian sets so much more evenly in
   them than in a Latin face with Cyrillic bolted on. Each weight/style is
   split into a cyrillic and a latin file — the browser only fetches the
   one it actually needs for the characters on the page. */
