1/**
2 * Evita reidratar carrinho abandonado após esvaziar localmente e sair rápido de /carrinho.
3 * Patch leve no $pd — não exige rebuild do main.js.
4 *
5 * Proteções:
6 * - flag de esvaziamento em localStorage (WebViews como Instagram não persistem sessionStorage)
7 * - cancelamento de POSTs stale (last-write-wins)
8 * - sync vazio com retry antes de navegar ao cardápio
