/* ========================================
   TOAST NOTIFICATIONS — estilo "claro premium"
   ----------------------------------------
   Feedback de erro/sucesso disparado por FNB.toast (core.js).
   Pilha fixa no canto superior direito: cada toast tem chip de ícone,
   título + mensagem, botão de fechar e barra de progresso do tempo
   restante. Depende apenas dos tokens de colors.css/inline.css.

   --transition-normal vive em theme.css, ausente nas páginas logadas;
   por isso as transições usam fallback explícito.
