   NauasX — Tema Cloud (padrão visual unificado)
   Extraído do Nauas Cloud para padronizar o NauasX legado (Flask).

   COMO USAR NO FLASK:
     1. Copie este arquivo para  static/nauasx-tema-cloud.css
     2. No <head> do base.html, DEPOIS do CSS atual:
          <link rel="stylesheet" href="/static/nauasx-tema-cloud.css">
          <link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=IBM+Plex+Sans:wght@400;500;600;700&display=swap">
     3. Use as classes daqui nas telas novas; as antigas vão sendo convertidas
        aos poucos (os tokens não conflitam com as classes tn-* / ag-* atuais).
