/* ===== Respaldo tipográfico con métricas igualadas =====
   El texto se pinta primero con la fuente del sistema y cambia a la web cuando
   llega. Si las dos no ocupan lo mismo, todo se recoloca en ese instante: eso
   provocaba un CLS de 0,145 en la portada (medido con y sin fuentes web: sin
   ellas el CLS era 0).
   Estos descriptores ajustan Arial para que ocupe exactamente lo mismo que
   Inter y que Space Grotesk. Los valores salen de comparar las métricas reales
   de cada archivo: ancho medio de minúsculas, ascendente y descendente.
   Cuesta cero bytes y no cambia nada visualmente. */
