   Nível 0: cabeçalho do grupo (visualmente igual aos demais

   Nível 1: categoria → abre seus produtos.
   Nível 2: produtos (links diretos).
   A abertura anima a altura com grid-template-rows 0fr→1fr,

   as categorias têm de 2 a 8 produtos cada). Navegadores
   antigos que não animam ainda abrem/fecham normalmente.
