/* =============================================================================
 * Maplable self-hosted fonts (perf pass 2026-04-29)
 * Replaces 3 third-party stylesheet requests (fonts.googleapis.com x2 +
 * api.fontshare.com) with a single same-origin CSS file → drops 2 DNS+TLS
 * handshakes (~150-250ms cold) and one whole external origin from CSP.
 *
 * Format: VARIABLE woff2 — one file per family per unicode-range covers
 * every weight we need (Inter 100-900, JetBrains Mono 100-800, Geist 100-900).
 *
 * Subsets: latin + latin-ext only. Drops Cyrillic, Greek, Vietnamese, etc.
 * to ~1/3 the byte count of full Google Fonts payload. The landing page is
 * English; if/when we localize, add the missing subsets back as additional
 * @font-face blocks pointing at additional woff2 files.
 *
 * unicode-range strings copied verbatim from the live Google Fonts CSS so
 * the browser will only fetch the latin-ext file when a Western European
 * accented character is actually used (rare on this page).
 *
 * font-display: swap — paint with the system fallback first, swap in the
 * real font once it's downloaded. Zero FOIT, slight FOUT.
 *
 * size-adjust / ascent-override / descent-override / line-gap-override —
 * NOT applied here. We could later use Andrew Caceres's font-fallback
 * generator (npm: fontaine) to synthesize a metric-matched system fallback
 * face that eliminates the FOUT shift. Defer to a follow-up if we measure
 * a perceptible reflow.
 *
 * Files live at /css/fonts/*.woff2 and are aggressively cached by .htaccess
 * (max-age=31536000, immutable — same-origin, content-addressed by name).

   Geist Variable from Vercel covers the full Latin set including Western
   European extended characters (the file ships without separate subsets),
   so a single @font-face is enough for both latin and latin-ext use cases.

   reachable codepoint space, falling back through font-family stack only
   for codepoints the file truly doesn't contain. */
