/* ============================================================
   Caies IPTV — Design System
   Paleta: índigo profundo + verde-limão vibrante (nova, distinta
   dos 7 projetos anteriores: vermelho/preto, amarelo/navy/vermelho,
   violeta/dourado, verde/laranja, navy/ciano, grafite/magenta,
   verde-petróleo/âmbar).
   Layout: navegação mobile como MEGA MENU EM GRADE (painel dropdown
   sob o cabeçalho, não tela cheia, não gaveta, não sanfona no fluxo);
   hero com faixa de categorias/pílulas decorativas; cards com dobra
   de canto (corner-fold) contendo o ícone; compatibilidade como
   ACORDEÃO POR DISPOSITIVO (cada aparelho expande mostrando os apps
   recomendados); planos em LISTA-ACORDEÃO vertical (não grid, não
   tabela, não carrossel); FAQ com sumário lateral por categorias
   (sticky no desktop, pílulas de âncora no mobile); pequena faixa de
   confiança compacta junto aos planos (variação: nem seção grande,
   nem ausência total); rodapé com wordmark gigante de fundo.
