   ------------------------------------------------------------
   La página se sirve hoy sin ninguna petición a terceros, lo que permite
   afirmar en la política de privacidad que no se comunican datos a
   proveedores externos por el simple hecho de visitarla.

   Para usar Inter y JetBrains Mono con su diseño original:
     1. Ejecuta scripts/get-fonts.ps1 (descarga los .woff2 a assets/fonts/).
     2. Descomenta el bloque siguiente.
     3. Añade en el <head> de cada página, antes de styles.css:
        <link rel="preload" href="assets/fonts/inter.woff2" as="font"
              type="font/woff2" crossorigin>

   NO descomentar sin los archivos: provocaría un 404 por carga de página.
