 * Testes de caminhos-base de WorkModalities e OfferCard: a entrada das ofertas (Reveal, CSS), o toque e o passe do
 * mouse (classes cv-press e cv-lift, sem foco nos cartões), as quatro ofertas (nome e "O que você recebe" vindos de
 * `serviceOffers`, foto do case, vídeo ou ilustração, botão que abre o formulário com o tipo escolhido, "Primeiro passo"
 * uma vez só depois dos cartões), a faixa da nota fiscal acima deles, o estilo único de cartão, o texto de pelo menos
 * 15 px e a lista compacta de etapas.
 * Nada de animação em JavaScript: o movimento reduzido é tratado pelo CSS (globals.css e conversion.css).
