     indigo-500 dá 4.467:1 sobre branco — reprova o piso AA de 4.5:1 por 0.033.
     Não é preciosismo de número: `--brand` é cor de TEXTO em todo `<a>`, nos
     ícones de título e no fundo do botão primário (com texto branco por cima,
     e contraste é simétrico — o botão media o mesmo 4.467). O indigo-600 sobe
     para 6.288:1 e mantém a identidade: é o degrau que a paleta já usava como
     `--brand-strong`, não uma cor nova. O tema ESCURO não muda: lá o
     `--brand` (#818cf8 sobre #14161d) já dá 6.057:1. */
