/* =============================================================
   Kalculia UI — sistema de diseño compartido («Fintech vivo»)
   Lo cargan todas las páginas antes de su propio styles.css, que solo
   contiene lo específico de cada herramienta.

   Espaciado: escala única de base 4px (--s-1 … --s-8). Toda separación
   entre bloques, rellenos y huecos de rejilla sale de esta escala, para
   que márgenes y alineaciones sean idénticos en todas las páginas.
   Simetría: las rejillas de tarjetas usan filas de igual altura y los
   contenedores comparten un único ancho máximo, alineado con la cabecera.
