Three layers. One byte-identical wire format.

Protocol SDKs sit at the base. Reviews widgets (QRP-0001) are drop-in UI on top. Platform plugins wrap the widgets so non-engineers can install them from an app store. Signing is byte-for-byte identical from Python at the lowest layer all the way up to a WordPress admin panel.
