/* Reparto de líneas: los titulares reparten el ancho a partes iguales en lugar
   de dejar una línea larga y otra corta. .faq-question entra por herencia: el
   reparto no se aplica a la caja flex, sino al bloque anónimo que envuelve su
   texto, que es donde hace falta.
   Esto iguala líneas, no evita la palabra sola al final: el navegador elige el
   corte por anchura, y entre «Operating Room / Fundamentals» y «Operating /
   Room Fundamentals» prefiere el primero justo porque iguala mejor. De que
   ninguna caja cierre con una palabra suelta se ocupa assets/js/huerfanas.js. */
