 * Player box: a pagina inteira e o player.

 * Ele e usado em caixas de tamanhos bem diferentes, entao quase nada aqui tem
 * medida fixa: a capa, o texto e os botoes saem de clamp() sobre a menor
 * dimensao da caixa, e o cartao deita ou fica de pe conforme o espaco.
 *
 * O fundo e a propria capa da musica, borrada e escurecida; sem capa fica o
 * degrade escuro.
