/* Omnia Languages — omnia-languages.com

/* Fonts are self-hosted, not loaded from Google.
   Requesting them from fonts.googleapis.com sends every visitor's IP address to Google,
   which needs a lawful basis under the GDPR and is what LG Munchen I penalised in
   3 O 17493/20 (20 Jan 2022) — the court's own reasoning being that the files can just as
   well be served locally. It would also contradict /privacy, which tells visitors the
   project has no third-party libraries and no server of its own.

   Both families are SIL OFL 1.1, which permits redistribution; the licence requires the
   copyright notice and licence text to travel with the files, so OFL-newsreader.txt and
   OFL-publicsans.txt sit beside the woff2 in assets/fonts/. Neither family reserves a
   Reserved Font Name and the files are unmodified, so no renaming is required.

   These are variable fonts: one file per family per subset covers every weight the site
   uses, which is why a 500 face is not a separate download. The latin-ext files are only
   fetched when a page actually uses a character in that range. Newsreader's italic has no
   wght axis upstream, so italic is 400 only — as it was with the Google-hosted CSS. */
