/* ============================================================
   Self-hosted fonts (SIL OFL). Served from /fonts; the
   above-the-fold faces are preloaded — in App.razor for the
   live site, in NewLanding's <HeadContent> while /newlanding
   is in preview. font-display: swap is the safety net; with
   preload the swap happens before paint.

   Two type systems live here during the transition:
     · Space Grotesk + Inter — the live site. Retire both, and
       their preloads in App.razor, once the last page that
       uses them is restyled.
     · Archivo + IBM Plex Sans + IBM Plex Mono — the new system
       (The Front Door Rev. 17). Declarations download nothing
       until a rendered rule references the family, so they
       cost the live pages zero bytes.

   src note. One plain format('woff2') source per face, variable
   or static: every browser that renders variable fonts accepts
   it, and it is the one form no CSS bundler or minifier trips
   on. (The old 'woff2-variations' format string is non-standard.)

   Licence. Archivo (Omnibus-Type) and IBM Plex (IBM) are both
   SIL Open Font License 1.1: free for commercial use, including
   web embedding. The OFL asks that the copyright and licence
   text travel with the font files — keep OFL-Archivo.txt and
   OFL-IBM-Plex.txt beside the woff2 files in /fonts (they ship
   as LICENSE in the Fontsource packages). Nothing needs to be
   shown on the site.

   Files are Fontsource builds, latin subset:
     @fontsource-variable/space-grotesk, @fontsource-variable/inter
     @fontsource-variable/archivo
     @fontsource/ibm-plex-sans   400 · 500 · 600 · 400 italic
     @fontsource/ibm-plex-mono   400 · 500 · 700
   The latin subset does not carry → (U+2192) or № (U+2116);
   those glyphs render from the fallback stack by design.
