/* ISO 15118 - Plug&Charge Lab by V2C — identidad visual V2C.
 *
 * Blanco y negro, editorial, Montserrat, mucho aire. El color no se usa: la
 * estructura sale del espaciado y de reglas finas, no de cajas ni de sombras.
 *
 * Tema claro unico y deliberado. El logotipo de V2C es la version negra, y la
 * marca prohibe ponerlo sobre fondo oscuro o recolorearlo; con un solo tema claro
 * el logotipo siempre cae donde debe y no hay que inventarse una variante.
 *
 * El estado (caducado, roto) tampoco va en color: se marca invirtiendo a negro
 * macizo, que en un sistema monocromo es la forma de gritar.
