Identidad: símbolo, logotipo (Dracutaz) y firma; dibujo nuevo con presencias; League Gothic
- docs/marca: símbolo (calle-persona) en positivo, negativo y naranja; logotipo en una y dos líneas, convertido a trazados; hoja de marca y alternativas de pincel (solo uso personal) - docs/calle.svg: calle pintada que se disuelve, sin edificios; las presencias forman una persona grande con el puño en alto - maqueta: firma en la cabecera, portada con lema y dibujo; League Gothic en lugar de New Rocker, Anton y Special Elite
