/* ═══════════════════════════════════════════════════════════════════════
   AudioLoop: a rádio que compõe música sem parar. Escuro, com a cor da estação (--st e --st2) no visualizador, nas teclas e nos botões.
   A cor do projeto (--accent, --accent-2) vem do <html>; a da estação, do <main>, e a troca de estação só reescreve essas duas variáveis.
   Contraste: texto claro sobre fundo escuro (>= 7:1); o texto dos botões coloridos é escuro (>= 7:1 sobre as cores das estações).
   Movimento: juice.js põe data-motion="reduced" no <html> (Animações desligadas ou sistema pedindo menos movimento).
