 * Torre de Control GIRAG — hoja de estilos compartida (dashboard.html + vuelo.html).

 * Tokens tomados literalmente de DESIGN.md ("AeroLogic Professional"):
 * navy #000062 como primario (headers/navegación), naranja #fd7c11 como
 * acento (CTAs/alertas), Inter como tipografía, radios suaves (4-8px),
 * tarjetas blancas con borde gris claro, zebra striping en tablas.
 * No se usa ningún framework de CSS (ver decisión de tecnología en el
 * informe): variables + clases utilitarias mínimas, pensadas primero para
 * una pantalla grande/proyector (alta densidad, texto legible a distancia)
 * y que no se rompan en una laptop.
