   Atendimento com IA (só na home)
   Seção presa na tela (sticky), no mesmo esquema da timeline do Processo:
   o scroll vertical troca a tela "antes" (cliente esperando) pela "depois"
   (IA respondendo). No celular e com movimento reduzido não prende: mostra
   direto a conversa com a IA. Lógica em js/atendimento.js.
