/* ==========================================================================
   Vecta ERP — Estoque Megalab · folha de estilo do painel administrativo
   --------------------------------------------------------------------------
   Estende e sobrescreve o admin do Django. Organizado em seções:
     1. Tokens (:root)              5. Componentes do dashboard (.megalab-*)
     2. Base (body, links, tabela)  6. Relatórios e tabelas responsivas
     3. Header / navegação          7. Login e auth (.vecta-*)
     4. Botões e formulários        8. Feedback (toasts, loaders, spinner)
                                     9. Responsivo (media queries)
   Convenção de prefixos:
     .megalab-*  → telas internas (dashboard, relatórios)
     .vecta-*    → identidade de marca (login, rodapé)
   Os nomes de classe são consumidos pelos templates — não renomear.
