 * 🎨 UnifespIA – Design System v1.0
 * 📄 Arquivo: auth.css
 * 📍 Localização: public/assets/css/auth.css
 * 🎯 Objetivo: Estilos de autenticação (Login/Register/Recover/Token) com suporte
 *             total a Dark/Light Mode + feedback de validação consistente.
 * ❓ Por quê:
 *    - Padronizar UI das páginas de auth (card centralizado, navbar, footer)
 *    - Garantir compatibilidade com Bootstrap + overrides necessários
 *    - Evitar “Dark preso” quando o tema estiver Light (botões/inputs)
