/*
 * Hub de Produtos SuperFarma — identidade visual do painel (§75).
 *
 * Paleta petróleo com acento laranja queimado: distinta dos outros módulos da
 * rede (Consulta de Estoque usa índigo, PixSF usa azul/verde), para que dê
 * para saber em qual sistema se está apenas pela cor.
 *
 * Escrito à mão de propósito: a hospedagem compartilhada não tem Node, então
 * qualquer pipeline de build viraria dependência frágil no deploy.
