/* ===========================================================
   Bad News — sistema visual.

   Três decisões sustentam o resto:

   1. PROFUNDIDADE POR CAMADAS, não por sombras. A barra lateral é a
      superfície mais funda, o conteúdo é a mais alta. Cada camada sobe um
      degrau de luminosidade e ganha um fio de 1px. Sombra fica reservada para
      o que realmente flutua sobre a interface — menus, modais, avisos.

   2. O ACENTO É RARO. Roxo só aparece no que está ativo agora ou no que a
      pessoa deve tocar em seguida. Interface de chamada de voz passa horas na
      tela; cor demais cansa e some o significado.

   3. TUDO NUMA GRADE DE 4px. Espaços, raios e tamanhos de ícone saem da mesma
      escala — é o que faz o conjunto parecer desenhado e não montado.
