/* FlexiHTV Gateway — painel de operação inspirado num rack de headend.
   Visual da marca FlexiHTV: fundo claro, cabeçalho em ardósia com o logótipo branco e o âmbar (#f59e0b) como acento.
   Sem recursos externos (a letra DM Sans e o logótipo vão com o gateway): tem de funcionar numa rede de hotel isolada. */
