/* =====================================================================
   iMoon ERP · portada
   Colores, letra y superficies del programa (OddsCRM.UI): los azules
   (#48E2F6 → #1478EE, y el azul hondo #005BFF), blanco frío en claro y el
   azul noche en oscuro, Montserrat y el
   relieve suave del acceso, en tono oscuro y claro. La luz de fondo de la
   portada y del cierre usa la misma paleta.

   Esquinas: tarjetas 24 px, marcos 16 px, casillas 14 px, botones en
   píldora. Movimiento: sólo transform y opacity; todo lo que se mueve
   vive al final, y con «reducir movimiento» la página queda quieta.
