/* Estilos de las paginas internas de estudiobielli.com.ar (ARQ-562).

   La home mantiene su CSS en linea a proposito: es la pagina que mas importa
   para el LCP y no conviene sumarle una peticion bloqueante. Lo unico que se
   repite entre los dos lados son las variables de color y la cabecera; el
   resto de este archivo es propio de las fichas y de las landings. */
