 * Cores tiradas do logo: o degrade azul-mare -> ciano das tres barras.
 * Tipografia: Barlow (sinalizacao esportiva), servida daqui mesmo, sem
 * Google Fonts (nada de IP do usuario indo para terceiro).
 * O elemento marcante e a tela de execucao: barras inclinadas como as do
 * logo marcando as series, e o alvo em numero grande. O resto e quieto. */
