详细信息

Owner ruling D-W15-2: hosting, free trials and domains go through ONE public checkout, so a visitor never has to sign up in the app before they can buy. The price is computed by the server from the pinned plan VERSION in the cart's own currency; anything sent by the client is ignored. A basket holds one plan at a time, because a subscription governs the org rather than a line. `trial: true` prices the line at **zero** and is refused (`422`) on a plan that does not offer a trial — eligibility is read from the catalogue, never taken on trust.
