The offer identifier is the stable part

A printed code redirects to /d/<id>/ and nothing else about it is load-bearing. Not the host, not the path above it, not a word of the copy.

That is deliberate, and it is the one piece of engineering this site does purely because of a disagreement. A ruling of 10 September placed a storefront under the risk product rather than on the platform domain. The instruction in hand overrode it and named this host. The ruling stands on the record, unedited, and the build treats the host as moveable: every internal link here is relative, the host appears in no sentence of copy, and the identifiers above do not change. If the site moves, it costs a DNS record and no reprinting. {{claim:domain-ruling-overruled}}
