   RCM Advocacia — Chatbot de triagem
   -------------------------------------------------------------
   Usa as variáveis de tema já existentes (index.html e
   edu-styles.css). Onde uma variável só existe na home, há
   fallback literal para as páginas educativas não quebrarem.

   Nada aqui altera estilo de elemento fora do widget, exceto o
   deslocamento do botão flutuante do WhatsApp — aplicado só
   quando o body recebe .rcm-has-chat (ou seja, com o chatbot
   ativo), para o rollback ser instantâneo.
