Verify a Colophon case

Everything runs in this page, on your machine. Nothing is uploaded, and it works with no network at all.

This is a convenience copy, and it is not the one that travels. A case carries its own verifier inside it — that copy is what a reader who was handed a document already has, and it is the one to use if you would rather not trust a page served by us.

The two differ in chrome and palette only. What they check is the same code, built from the same source, and both digests are published.
