/* =====================================================================
   SenDocs — Tema Moderno 2026 (REDESIGN VISÍVEL)
   ---------------------------------------------------------------------
   Esta camada é carregada DEPOIS do <style> inline do index.html.
   Diferente da versão anterior (que só re-declarava tokens quase
   idênticos e por isso não mudava nada no modo claro), aqui os
   COMPONENTES são re-estilizados diretamente, com seletores
   específicos e !important nos pontos-chave (fundo, header, nav ativa,
   cards, botões), garantindo override do CSS inline extenso.

   REGRA DE OURO: nenhum hook de JS é tocado. Usamos exatamente as
   MESMAS classes/IDs já presentes no DOM (.header, .header-content,
   .header-icon, .nav-tabs, .nav-tab, .stat-card-pro, .chart-card-pro,
   .card, .section, .btn*, .form-control, .table, .badge, etc.).
   Markup, onclick, data-attrs e URLs /api permanecem intocados.
   ===================================================================== */
