Verify an Ember-stone

Tap the stone against a phone and this page opens by itself, carrying a signature the chip composed a moment ago. Typing a serial instead is a ledger lookup — useful, but it attests nothing. Only a tap can attest.

The verifier returns three fields and stores no request metadata — no address, no device, no location. If this page loads without a network, it is a cached copy of the record and is marked unverified until a signature can be checked.
