 * Self-hosted @font-face declarations (fonts mirrored from lovart.ai).
 *
 * This file intentionally lives in /public and is loaded via
 * <link href="/fonts.css"> in app/[locale]/layout.tsx instead of being
 * bundled into globals.css: in production the bundled CSS is served from
 * the CDN (assetPrefix), and a root-relative url("/fonts/…") inside CSS
 * resolves against the CSS file's origin — the CDN host, where /fonts/*
 * 404s. Served same-origin from /public, the URLs always resolve to this
 * site's /fonts/*.
 *
 * Each web font ships a paired `… Fallback` face that maps local(Arial)
 * with metric overrides — copied verbatim from lovart — so the swap from
 * fallback → web font causes no layout shift (CLS≈0). Override values are
 * intentionally not "round". The @theme `--font-*` tokens referencing these
 * families stay in app/globals.css.
