One detail worth handling on the live-price side is out-of-order quote responses: if option changes fire several quote calls, a slower earlier response can overwrite a newer price unless requests are aborted or responses are sequenced against the current configuration.
Separating information leakage from price integrity is useful. I would make the quote reference carry an explicit pricing-version and expiry policy too: if the rules change between preview and acceptance, silently recomputing can surprise the buyer even when the server is authoritative. A clear “quote expired, review the new total” step keeps the security boundary and the buying experience aligned.

The integrity half is the one I keep underestimating. I used to think hiding the price list was the whole problem, then realized a tampered total on submit is worse if the server just trusts it. Sending the config and letting the server recompute on confirm is the version I would actually ship. The bit about a price change being a data change, not a deploy, would have saved me a few Friday releases.
