   Companhia IPTV — Design System
   Paleta: quase-preto neutro quente + azul vívido + areia dourada
   (nova, distinta dos 12 projetos anteriores: vermelho/preto,
   amarelo/navy/vermelho, violeta/dourado, verde/laranja,
   navy/ciano, grafite/magenta, verde-petróleo/âmbar,
   índigo/verde-limão, terracota/dourado, roxo/rosa-neon/ciano,
   navy/laranja/amarelo — nenhum projeto anterior usou AZUL como
   cor de destaque/CTA principal).
   Layout: navegação mobile como TRILHO VERTICAL DE ÍCONES sempre
   visível (expande em largura para revelar rótulos — não é
   dropdown, tela cheia, gaveta, bottom-sheet, sanfona, tab-bar,
   mega-menu, fab-leque, dock horizontal ou busca); hero com um
   LEQUE DE CARTÕES estático (sem rotação de palavra, sem ticker,
   sem marquee); cards com ABA INFERIOR (ícone projetado para fora
   da borda de BAIXO do card, ao invés do topo); compatibilidade em
   GRADE DE CARTÕES QUE VIRAM (flip 3D ao clicar, revelando o texto
   no verso); planos em BARRAS DE COMPARAÇÃO horizontais
   proporcionais ao valor médio mensal, com clique para expandir
   detalhes; FAQ em ACORDEÃO HORIZONTAL de colunas por categoria
   (rótulo vertical quando recolhida); rodapé de UMA COLUNA SÓ, sem
   grade, com todos os links em uma única linha central.
