/* Movimento reduzido.

   Antes aqui havia um `* { animation-duration: 1ms !important }` que
   desligava TUDO — inclusive o giro do botão de carregar e o efeito de
   entrada do aviso, que são feedback de interface e não decoração. Muitos
   ambientes (Chromium headless, vários Windows) reportam `reduce` por padrão,
   então o efeito de ficar "correto" era a página inteira parecer sem vida.

   Agora só sai o que é decorativo e repetitivo. */
