/* =============================================================================
   Adesivo Aí — Papel & Tinta
   =============================================================================
   Direção: o mundo do adesivo é a faca de corte e a tinta CMYK.

   - Superfície = papel (não creme; papel é mais frio e mais limpo)
   - Acento = magenta de processo, a tinta que diz "gráfica"
   - Assinatura = a linha de corte tracejada, que aparece nos cards e no hero

   Magenta é usado com avareza: em botão de ação, em preço e na linha de corte.
   Se ele estiver em tudo, ele não está em nada.
