Browser-based Oblivious HTTP demo — RFC 9458. Three parties, split knowledge: relay sees your IP, gateway sees your request, neither sees both. Real HPKE encapsulation over Binary HTTP. Flip the collusion toggle and watch the guarantee evaporate — it was always an organizational assumption, not a mathematical one. No backends. No simulated math.
