/* =====================================================================
   THEME 2026 — Design System único para todo o projeto
   (site do aluno + painel administrativo)

   Como usar:
   - Salve este arquivo em /assets/theme-2026.css na raiz do projeto.
   - Nas páginas da raiz:        <link rel="stylesheet" href="assets/theme-2026.css">
   - Nas páginas dentro de /admin: <link rel="stylesheet" href="../assets/theme-2026.css">
   - Carregue DEPOIS dos CSS antigos (base_packaged.css, geral.css, etc.)
     para que estas regras tenham prioridade e o visual antigo não conflite.
   - Este arquivo NÃO depende de nenhum framework externo (sem Bootstrap,
     sem Tailwind) — é CSS puro com variáveis, então funciona em qualquer
     página PHP existente sem precisar de build step.
