The author found copying the release of the round tedious. A button,
"Pedir la firma a drand", fetches it from the three public relays of
the CLI of the reference, as its client does: raced, 6 s, at most
8 KiB an answer, no redirects, and the randomness checked against the
signature; step 10 still verifies the signature with the pinned key,
so a relay cannot make the page accept a false one. It is the only
connection the page makes to another site, and only on that click: the
CSP allows those three origins in connect-src, check-build.mjs
requires exactly them, and the footer says so. Pasting by hand still
works. Checked in Chromium: api2.drand.sh gave the release of round
32668196 and the capsule opened.

A prerendered static site (adapter-static) with a landing page and
/inspect, which runs spec §63 steps 1 to 8 on a .dkc chosen with the file
picker, dropped anywhere on the page, or taken from the official fixtures
bundled at build time. It shows every step, the decoded header, the unlock
date in UTC and local time, and each extension's id, version, criticality,
length and hex, with a text view and an informative CBOR diagnostic view,
all escaped and labelled as unauthenticated before step 15. Copiar JSON
copies the exact "datekeys inspect -json" view.
No network: a hash-mode Content-Security-Policy with connect-src 'self'
is the first element of every page, and scripts/check-build.mjs verifies
it, the fixtures and the absence of external URLs after every build.
Large files are read only up to what steps 1 to 8 need.
Reviewed for design and accessibility (WCAG AA contrast, keyboard,
focus, live status, 360 px), security and correctness; 262 tests pass,
svelte-check has no warnings.
