/* ======================================================================
     TOKENS — nomeados pelo papel, nunca pela aparência.
     Quatro sistemas independentes, porque três coisas diferentes nunca
     podem depender da mesma codificação visual:
       · direção do efeito   → posição num eixo + palavra + par divergente frio/quente
       · certeza da evidência→ escada de quatro casas, monocromática
       · estado da interface → verde/âmbar/vermelho, exclusivo da ação do leitor
       · procedência         → monocromática + glifo + palavra
     E duas vozes, que são a espinha do produto:
       · voz do leitor    (ameixa)  — o que é seu
       · voz canônica     (índigo)  — o que o campo diz
     ====================================================================== */
