 * Página pública de inicio (rediseño autorizado por Fernando el 14 de octubre de 2026, inspirado en stripe.com/es/payments).
 * Colores de la firma: tinta #05232d, turquesa #00c8ce, petróleo #0091a6 y sus derivados. Letra del sistema.
 * Efectos: degradado animado en WebGL (inicio.js) con respaldo en CSS, escena en 3D que sigue al cursor, tarjetas que se
 * inclinan, capas y anillos en 3D y apariciones al bajar. Con «reducir movimiento» del sistema, todo queda quieto.
