/* Solo latin + latin-ext. Los subsets cirilico/griego/vietnamita del bundle
   original (~154 KB) son inalcanzables en espanol: a-z, aeiou acentuadas, n,
   u con dieresis y los signos ¿¡ caen todos en U+0000-00FF, y la raya (U+2014)
   en U+2000-206F. unicode-range hace que latin-ext no se descargue nunca en
   la practica, pero queda como seguro ante un nombre propio con caracteres
   como l o un simbolo de moneda.

   font-weight como RANGO (400 700) es deliberado: sustituye a las cuatro
   reglas identicas por subset que tenia el bundle. Con un valor unico, los
   pesos 500/600/700 caerian a negrita sintetica. */
