FONTS SHIPPED WITH THE WEBSITE AND WITH THE EXTENSION

  Geist and Geist Mono (https://github.com/vercel/geist-font). Copyright 2024
    The Geist Project Authors. SIL Open Font License 1.1.
    The website serves them from its own address (apps/web/public/fonts), and the
    extension packs the same files for its own pages (apps/extension/public/fonts;
    never for a chat page): the
    variable WOFF2 files of the Fontsource packages @fontsource-variable/geist
    5.3.0 (tarball SHA-256 533dd66117795ac12316fb05fce27736c4bc63c31613b302d0a5285ca3a291d7)
    and @fontsource-variable/geist-mono 5.3.0 (tarball SHA-256
    af7a9f156602b859efa95cd1acb824a5322c51a1eca53afb38ed033885736a70), unchanged,
    one file per Unicode block (Latin, Cyrillic, Cyrillic Extended). Taken once
    with npm pack on 2026-10-02; no package is a dependency. Both have every
    Kazakh letter (Ә Ғ Қ Ң Ө Ұ Ү Һ І, both cases). The licence texts are beside
    the files: geist-LICENSE.txt and geist-mono-LICENSE.txt.
