 * `hidden` no HTML tem de esconder de verdade.

 * O navegador aplica `[hidden] { display: none }` pela folha padrão dele, que
 * perde para qualquer regra de autor — e `.btn` define `display: inline-flex`.
 * O resultado: o botão "Tentar novamente" da página da rádio nascia com o
 * atributo `hidden` e aparecia mesmo assim, para todo ouvinte, desde o primeiro
 * carregamento. Um botão de socorro permanente na tela sugere que algo quebrou.
 *
