The context
A limited-edition clothing brand, with small drops that sell out. That model changes what the site has to do: it is not a permanent catalogue but a showcase for a batch — what is live today may not exist next week.

A cart without checkout
The cart exists and collects pieces, but the order closes on WhatsApp. For a small drop that is an advantage, not a limitation: availability can be confirmed before charging, which avoids selling a piece that ran out between the click and the payment.
Still in development — the catalogue and cart structure is in place; stock management per drop is what is missing.
