/* ==========================================================================
   dev.egv.es — hoja de estilos compartida
   Antes cada página (index / diagnostico / plan-economico) llevaba su propio
   bloque <style> de ~300 líneas casi idénticas. Este fichero las unifica: un
   arreglo aquí llega a las tres a la vez.

   Paleta navy/gold/ice del estándar `estandar-paginas-egv` (sección 6).
   Las variantes que sí difieren entre páginas van como clase modificadora
   (.steps-4, .price-table.t-precios, .price-table.t-compara), nunca
   redefiniendo la clase base.
