/* Plano B do link de e-mail ----------------------------------------------
 * Quando o navegador não abre o cliente de e-mail, o site oferece copiar o
 * endereço. São dois formatos:
 *   .email-fallback  painel sob o link que mostra o endereço;
 *   .email-toast     aviso flutuante para botões que só abrem o e-mail.
 * O painel usa a cor do contexto (rodapé escuro / página Sobre clara), por
 * isso `currentColor`; o aviso flutuante é sempre escuro, para ser legível
 * sobre qualquer fundo.
