/* ============================================================
   MB Soluciones — demo del panel de KPIs (/demo/dashboard)
   Dirección: "sala de mando". Un solo panel enmarcado sobre el héroe
   oscuro, con una única secuencia de carga orquestada: las fuentes se
   sincronizan, los KPIs suben, el gráfico se dibuja y cruza la línea
   de HOY hacia la previsión, el ranking crece y las alertas van
   entrando una a una. Sin librerías: SVG + CSS + JS vanilla.
   Depende de los tokens de style.css (se carga después de él).
