   ISpeedType — Tema inmersivo: GRAFITI CALLEJERO (Urban Vapor)
   Todo va dentro de body.theme-graffiti: sin la clase, esto no afecta a nada.

   Reglas de rendimiento que respeta este archivo (ver notas en styles.css):
     - nada de text-shadow ni animaciones por letra en el texto principal;
     - las letras solo cambian de color / fondo (se pintan, no recalculan layout);
     - los efectos de chorreo y spray son elementos reutilizables (themes/graffiti.js).
