   Ravi — painel do assistente de IA.

   O esqueleto (.assistant, .assistant-panel, .bubble, .chip) já vem do
   app.css; aqui entra só o que a conversa com IA trouxe de novo: corpo
   formatado, fontes citadas, bolha de recusa, indicador de digitação e a
   barra com contador. Tudo em variáveis do tema, para acompanhar as
   preferências de aparência de cada pessoa.
