   Mostrado no máximo 1x a cada 72 horas por usuário (ver app.js).

   CORES ADAPTATIVAS: nada de cor fixa. Toda a paleta é derivada de --gold,

   (azul/verde/ouro/branco/branco metálico/rosa metálico — ver
   forceApplyGradient em js/app.js). As superfícies e os tons semânticos
   (certo/evitar) têm variantes próprias para tema claro e escuro, garantindo
   contraste legível em qualquer combinação.
