/* ═══════ FONTS ═══════
   Self-hosted rather than pulled from fonts.googleapis.com: no third-party
   round-trip before the first paint, and no visitor IP handed to Google
   without consent. The files are copied out of node_modules at build time —
   see the passthrough mapping in eleventy.config.js.

   Both are variable fonts, so one file per family serves every weight. No
   unicode-range is declared: with a single file per family there is nothing
   to choose between, and glyphs the subset lacks still fall back per-glyph.
   Italics are synthesized, exactly as they were with the Google Fonts
   request, which never asked for an italic axis either. */
