/*
 * Compatibilidade de utilitários Bootstrap 4 para o site público.
 *
 * O site público carrega Bootstrap 3 (assets/bootstrap/) + o utilitário de
 * espaçamento próprio do tema (assets/css/default.css, escala em px de 5 em
 * 5: .pt-5 a .pt-200). Várias views (antigas e novas) usam classes de
 * utilitário do Bootstrap 4 (.d-flex, .d-none, .card, .form-check-*,
 * .col-xl-*, .mb-0..5, .my-*, .px-*, etc.) que não existem em nenhum dos
 * dois — ficam sem efeito, quebrando espaçamento/visibilidade/estrutura
 * (ex.: o loader "d-none" da página de produtos nunca ficava escondido).
 *
 * Este arquivo cobre só o que falta, sem redefinir nada que default.css já
 * cobre (steps de 5px pra cima em pt-/pb-/pl-/pr-/mt-/mb-) — evita colisão
 * de valores com o que as páginas antigas já esperam daquele arquivo.
