/* =========================================================
   AMPERSAND — glifo "&" visualmente más equilibrado
   =========================================================
   Space Grotesk (titulares) y JetBrains Mono (labels) tienen un glifo "&"
   poco refinado. Esta clase cambia ÚNICAMENTE ese carácter a Inter (ya
   cargada en el proyecto para el body), heredando tamaño, peso, color y
   letter-spacing del contexto donde se use — no altera ninguna otra
   tipografía global. Aplicar solo alrededor del carácter "&" real:
   E<span class="ampersand">&amp;</span>T
========================================================= */
.ampersand{
  font-family: var(--font-body);
  letter-spacing: normal;
  display: inline;
  margin: 0;
  padding: 0;
}
/* NOTA: en contextos donde el padre inmediato del ampersand es un contenedor
   flex con "gap" (.eyebrow, .mega__cta, .mobile-nav__sublink, .areas__item),
   dividir el texto en un <span> convierte cada fragmento en un ítem flex
   independiente y el gap del contenedor se aplica también alrededor de él,
   generando separación artificial ("E & T") o, en contenedores angostos,
   rupturas de layout. Por eso, en esos 4 contextos específicos el HTML NO
   envuelve el ampersand en <span class="ampersand"> — se deja como &amp;
   simple, que permanece como parte de un único nodo de texto y nunca se
   fragmenta en varios ítems flex. El span solo se usa fuera de contenedores
   flex con gap, donde el ajuste tipográfico es seguro. */
