/*
 * Inter - the site's global UI typeface.
 *
 * Self-hosted (fonts/inter/*.woff2) rather than pulled from Google Fonts:
 * this site already self-hosts its faces, and a local file removes an
 * external DNS + TLS round trip from every page load, keeps working if
 * fonts.gstatic.com is unreachable, and sends no visitor data to a third
 * party.
 *
 * One variable font covers weights 100-900, so bold/semibold text needs no
 * extra download. Two subsets are shipped: latin for everyday copy and
 * latin-ext for accented characters (Italian, European names). Non-Latin
 * scripts - Punjabi, Hindi - are deliberately NOT overridden here; the
 * unicode-range keeps Inter out of their way so they fall through to the
 * system faces that can actually render them.
 *
 * font-display: swap - text paints immediately in the fallback face and
 * re-renders when Inter arrives, so a slow font never blocks a child from
 * reading the question.
