/* DCX 404 - o painel
 *
 * Carregar depois de vendor/dcx-core/css/base.css e solo.css.
 * O desenho e o do mockup v4 aprovado (dcx-design/dcx-404/mockup-v4.html).
 * A primeira parte sao os componentes que o mockup pegava emprestados do
 * rj2000.css (marca, teclas, LED de 7 segmentos, grupos, knobs, jacks e pads),
 * copiados iguais para o 404 nao depender do repositorio do RJ-2000.
 * A segunda e o que e so do 404 (prefixo d4-), igual ao mockup.
