/* 0) FONTS ------------------------------------------------------------------
   Self-hosted so pages render with the right type offline and straight from
   file:// — no third-party request to Google's CDN (also keeps visitor IPs
   off it, which matters for a site serving the EU).
   Files pulled from the Google Fonts API, latin + latin-ext subsets only:
   enough for the Italian copy, and unicode-range means a page only downloads
   the subset it actually uses. Barlow ships as static weights; Inter is a
   single variable file covering 400-700.
   To add a weight: download its woff2 into assets/fonts/ and add a block here.
