   FUENTES — Neutrif (sans-serif)
   Convención: una font-family por peso (neutrif-light/regular/
   medium/semibold/bold) en lugar de una familia con varios pesos.
   local() permite usar la fuente instalada en el sistema si
   existe, evitando la descarga. font-display: swap evita el
   FOIT — el texto se muestra con la fuente fallback y se
   sustituye al cargar la web. Servimos woff2 (formato moderno,
   más comprimido) con fallback a woff para navegadores muy
   antiguos.
