/* Inter, self-hosted.
 *
 * WHY NOT @import FROM GOOGLE
 *
 * This used to be a single line in design-system/styles/globals.css:
 *
 *   @import url('https://fonts.googleapis.com/css2?family=Inter:...&display=swap');
 *
 * Three problems with that here:
 *
 *   1. Request chain. globals.css is loaded by a dynamic import() in main.js
 *      that fires AFTER the app mounts, and the @import inside it is another
 *      hop, and the CSS it returns points at a third host for the actual font.
 *      So the chain was JS -> CSS -> fonts.googleapis.com -> fonts.gstatic.com,
 *      resolving well after first paint. Text rendered in the fallback and then
 *      visibly reflowed once Inter landed.
 *   2. Third-party dependency on the critical path for text rendering.
 *   3. GDPR. Requesting a font from Google transmits the visitor's IP to Google;
 *      a German court (LG München I, 3 O 17493/20) awarded damages over exactly
 *      this pattern. Self-hosting removes the transfer entirely.
 *
 * WHAT IS HERE
 *
 * Inter v20 ships as a variable font, so ONE file per subset covers the whole
 * 100-900 weight axis. The three weights previously requested (400/500/700) are
 * all served by the same three files; `font-weight: 100 900` on each face tells
 * the browser it can synthesise any weight in range from it.
 *
 * Subsets are latin, latin-ext and greek. Greek is not decorative: the active
 * locales (en/fr/es) contain Σ and τ in stat/formula copy, and without the greek
 * face those fall back to a different typeface mid-sentence. The cyrillic and
 * vietnamese subsets are deliberately omitted; if USER_LANGUAGE_OPTIONS in
 * i18n/index.js ever gains ru or vi, re-run the fetch and add them here.
 *
 * `font-display: swap` keeps text visible during load rather than blanking it.
