/* ============================================================
   NEXUS v2 — bolinha orbital + chat
   ------------------------------------------------------------
   • O botão agora é uma esfera brilhante que flutua em círculos
     (360° no plano + sobe/desce) chamando atenção sem abrir nada.
   • O painel SÓ abre no clique e fecha de verdade:
     .nexus-panel[hidden] { display:none } — era isso que fazia
     o chat "não fechar" na versão antiga.
