   Paleta da marca: creme + laranja + verde-lima + roxo. Mobile-first.

   TEMA: claro (creme) é o padrão (:root). O escuro fica em [data-theme="dark"],
   ligado pelo botão de alternar tema (ver js/theme.js) e lembrado no
   localStorage. As cores de destaque (--purple/--orange/--lime/--green/--red)
   têm um valor mais escuro no tema claro (legibilidade em texto sobre fundo
   creme) e mais vivo no escuro.
