   LEVLUZ — Design tokens (identidade real da marca)
   Base: preto absoluto. Acento único: o verde da marca
   (#CEE637, extraído da logo), com tons derivados da mesma
   cor (mais escuros/mais claros) para dar profundidade sem
   introduzir outras cores. Os pretos aqui têm um leve
   tingimento verde em vez do cinza-azulado genérico de "dark
   mode".
