Cards keep their size, so nothing jumps when the real ones arrive.

Photo, name, price and the main button hold their places.

One question decides it: is the shape known?

Pending never looks positive: no tick and no green until the provider has answered.

Only the panel fails; the page around it stays usable.

The message sits in the form, the typed text stays, and a field says what to fix.

The buyer can retry while the hold lasts; when it ends the listing is released.

The listing waits in the exceptions queue and is never shown as passed.

The same dialog serves buying, offers, messages and saving; afterwards the person lands on the same listing.

Browsing stays open; the actions that need a confirmed address wait, with the reason beside them.

Open orders stay readable: label, tracking, payouts. Nothing new can start.

Someone else’s order looks exactly like one that doesn’t exist, so nobody learns what is there.

An operator sees only the items at their own hub, and nothing of payment.

Names the thing and what changed for the seller.

The next step is the rating, the only thing left to do.

Says why it was waiting and where it went.

A small thing gets a toast, not a page: it confirms and gets out of the way.
