This is the fallback page for the Keryx join URL (PROTOCOL §2). In a real
deployment it is shown only when the Keryx app is not installed; with the
app installed, the URL above would be handed to it and pairing would
continue there. The root anchor is derived from this page's origin
(/.well-known/keryx/root.json) — there is no metadata URL in
the payload.
Scan this code with the Keryx app to pair and subscribe. It is generated from this page's own URL, so it always matches the join link you opened.
