 *   Propósito: Substituir o CSS do Bootstrap 4.6 (EOL 2024) por uma   *
 *              implementação própria, compatível com a API de classes *
 *              do Bootstrap 4, mas visualmente alinhada ao Design     *
 *              System v2 (tokens CSS, fonte Inter, paleta CET).       *
 *                                                                     *

 *     - Este arquivo NÃO é um fork do Bootstrap. É código original.   *
 *     - Mantém os nomes de classe do Bootstrap 4 por compatibilidade  *

 *       markup das ~350 views existentes, que não precisam mudar.     *
 *     - bootstrap.min.css deve ser removido da ordem de carregamento. *
