   RAÍZ DEL DISEÑO — todo el look de la página se controla desde aquí.
   Este es el sitio PROVISIONAL de la agencia Nova Webs (no de un
   cliente). Paleta propia de "agencia/tech" — deliberadamente distinta
   de la cantera rosa de La Soñadora o el azul/rojo de Badillo, para
   que la identidad de la agencia no se confunda con la de un cliente.
   Conserva el motivo de arco (línea, no relleno) como guiño regional.
