/*
 * Modificador para títulos de página (ex.: "Esqueci minha senha", "Redefinir senha").
 * O ".kt-login-sgu__title" puro foi desenhado para o logotipo curto "SGU" (peso 900,
 * letter-spacing largo, gradiente); em frases mais longas isso fica pesado e menos
 * legível, então aqui usamos um peso/tamanho mais sóbrios e cor sólida (também evita
 * o problema de contraste de texto com gradiente para acessibilidade).
