/* ============================================================
   CARRINHO — ícone no header + painel lateral (novo componente)
   Este ficheiro só contém seletores novos (.cart-*, #cart*).
   Não sobrescreve nem modifica nenhuma regra existente do site,
   pelo que não altera o desktop já aprovado — apenas acrescenta
   o necessário para o carrinho, conforme pedido. Funciona em
   mobile e desktop.
