/*
 * a3erp.css — Estilos exclusivos de la plantilla A3ERP.
 *
 * Depende de main.css. Prefijo: a3-
 *
 * Palette de acento: azul índigo/pizarra para diferenciar de GMAO-GSAT (naranja).
 * Se mantiene --color-primary (#d88329) para CTA y highlights,
 * pero el hero y la sección de integración usan azul (#1e3a5f / #2563eb).
 *
 * Estructura:
 *   1. Hero
 *   2. Qué es (split + pilares)
 *   3. Áreas de gestión (grid 3×2)
 *   4. Funcionalidades técnicas (grid 2×2)
 *   5. Integración A3ERP + GMAO-GSAT
 *   6. CTA
 *   7. Animaciones
 *   8. Responsive
