   Lojinha Downloader - balcao de entrega por codigo.

   A pagina publica e operada em tres contextos: celular na mao, desktop
   e Smart TV com controle remoto. Isso guiou tudo aqui - alvos grandes,
   foco sempre visivel (o controle remoto navega por foco, nao por
   ponteiro) e o codigo como heroi da tela.

   Paleta: tinta profunda azul-esverdeada + laranja-sinal. O laranja
   carrega sozinho a acao ("baixar"); o verde so aparece em sucesso.
   Texto branco sobre o laranja cheio reprova contraste (~3:1), entao
   superficie laranja SEMPRE leva texto escuro (--signal-ink).
