/* ---------------------------------------------------------------- fonts --
   Self-hosted, not fetched from fonts.googleapis.com as the prototype does.
   Three reasons, heaviest first: the CSP is `default-src 'none'` and a remote
   origin in font-src would be the only hole in it; a third party would
   otherwise see every customer's IP on every page load; and a CDN outage would
   take the app's typography down with it.

   Files are fontsource 5.3.0, vendored under wwwroot/vendor/fonts/ with their
   licences beside them. woff2 only — every browser this app supports reads it,
   so the .woff siblings fontsource ships would be bytes nothing requests. (The
   Instrument Sans directory came across from manzil.my whole and still has
   its .woff files and its italics; nothing references them.)

   `font-display: swap` so text is readable on first paint. What shows during
   the swap is the fallback in --sans / --mono, which is why those are real
   stacks rather than a bare `sans-serif`.

   Two subsets each. latin-ext is not padding: a decoded IDN label can carry
   latin-ext characters, and a domain name renders in mono — without the subset
   a customer's own domain would fall back mid-string. Ranges are fontsource's
   own, unmodified. */
