/* ==========================================================================
   Uniframe Studio — Topbar v2 (camada de refinamento)
   Carregado DEPOIS de /styles.css. Só vale para <body class="tbv2">.
   O layout atual (/) não é afetado.

   O que muda em relação à topbar atual:
   1. Marca: logo "U" nova no rail; wordmark simples, sem o selo "Pro Multi-User".
   2. Breadcrumb: Uniframe Studio / Projeto — o projeto ativo vira o contexto da página.
   3. Modos no centro, em português e com estado ativo legível.
   4. Lado direito enxuto: status dos motores com cor real (verde só com 100%),
      Contas e Logs como ações discretas. Grid/List saem daqui porque já existem
      na barra da galeria logo abaixo (Grade/Lista).
