/* Reset importante: <button> tem padding padrão do navegador que NÃO é
   simétrico (mais nas laterais que em cima/embaixo). Com box-sizing
   padrão (content-box), esse padding se soma às dimensões fixas dos
   botões redondos (26px, 36px, 60px), deformando o círculo em oval e
   descentralizando o conteúdo. border-box elimina isso em qualquer
   botão do widget. O padding:0 fica de fora daqui de propósito - por
   ser regra com #id, tem especificidade maior que .zuzy-wa-cta e
   sobrescreveria o padding real do botão "Continuar no WhatsApp" (foi
   exatamente esse bug que aconteceu na v1.3.4). Cada botão circular
   zera o próprio padding individualmente, abaixo.
