/* Pla B Solucions — colorimetria FOSCA (fons negre, lletres blaves), a partir del logotip original.
   Colors del logotip (mostrejats; substitueix-los pels codis oficials si en tens):
   blau elèctric #0101FF · cian #39D9FB · verd menta #66FECB.
   Logotip: versió per a fons negre ("PLA" en blanc), amb fons transparent generat a partir del fitxer original.
   Contrast: el blau elèctric #0101FF sobre negre no és llegible com a text (2,4:1), per això el text blau
   fa servir el cian i un blau clar de la mateixa família; el #0101FF queda per a botons (amb text blanc) i detalls. */
