/*
 * SOS AUDIT — estilos base del frontend.
 *
 * Identidad de marca tomada del logo real (assets/img/logo.jpeg): navy +
 * azul vívido + gris pizarra. Layout del Dashboard (sidebar oscuro
 * agrupado, KPIs, línea+donut, tabla/impacto/alertas) tomado como
 * referencia visual de una pantalla de ejemplo (ver docs/08-dashboard.md:
 * "toma como referencia visual las pantallas proporcionadas de SOS
 * Audit, sin copiar marca, identidad ni contenido") — nombre, textos y
 * datos son los nuestros, ficticios.
 *
 * Nota de nombre: el logo dice "SOS AUDIT"; la documentación del
 * proyecto (CLAUDE.md, docs/) usa "BINTE AUDIT". Pendiente de
 * confirmación (ver frontend/README.md).
 *
 * Un solo tema (claro para el contenido, sidebar oscuro por diseño) —
 * decisión deliberada para esta fase, no modo oscuro completo de la app.
