Two problems bundled into the branded error page:
1) "fetch failed" on no network — the tab kept falling through to
name-not-registered (and other "we asked and got nothing" verdicts)
because a totally offline browser can't reach the beacon to know.
Add a first-class `offline` kind that runs before every other
verdict: navigator.onLine === false wins; the page says "You appear
to be offline" and keeps the address so the user can Retry after
reconnecting.
2) Typos on BCNR names (games.x when they meant game.x) — the page
only offered Search / Register. Now the page asks main for the top
near-matches from the warm sharedIndex (Levenshtein ≤ 2, same TLD)
over an origin-gated `error-bns-similar` IPC. Up to three matches
render as chip-links; clicking one retries at that host, preserving
the original path. Works offline too — the index is local.
Origin-gate on the IPC uses the existing isErrorPageSender check, and
error-preload.js exposes only the invoke — no arbitrary index access.

Chromium's default 'This site can't be reached' replaced with a Theseus-
themed error page. did-fail-load on every tab's webContents (main frame
only, non-ignorable code) routes the tab to error.html with the
attempt URL, host, error code, and description as query params. The
page keeps t.url pointing at the failed URL so the address bar shows
what the user typed and they can edit + retry - refreshTabUrl's
existing file:// skip means the error page's own path never leaks
back into the bar.
Five kinds, chosen by pickErrorKind(code, host):
name-not-registered BCNR-eligible host + ERR_NAME_NOT_RESOLVED.
Says "no BCDN record on chain, no clearnet host
either." Offers Register on Sirius + Search +
Retry + Home.
name-unreachable ERR_NAME_NOT_RESOLVED on a non-BCNR host. DNS
failed - offers Retry + Search + Register +
Home.
unreachable CONN_REFUSED/RESET/TIMED_OUT/CLOSED/NETWORK_CHANGED.
Offers Retry + Tor guide + Home.
tls ERR_CERT_* range (-200..-299). Offers Retry +
Home.
generic Everything else.
home-preload.js gains `window.errorpage` alongside `window.home`. Both
APIs are sender-URL-gated in main - a random page seeing the shape
can't invoke them (isErrorPageSender / isHomePageSender). The external-
open handler additionally allowlists Silent Mode domains only.
package.json build.files gets error.html + error-preload.js so
electron-builder actually bundles them (GOTCHAS rule: an unlisted
runtime-loaded file silently opens blank).
Ship pages (releases-manifest.json, tools/index.html, releases/index.html,
site-theseus-x/index.html) updated to 0.1.3 with the new hashes.
DEPLOY STATUS - blocked on VPS SSH: my IP was hit with a full-port ban
mid-turn (likely fail2ban from the burst of scp during the 0.1.0-0.1.2
iterations). Site pages/manifest/installers are committed locally but
NOT yet on dl.silentmode.st or the Sia mirror. Live still reads 0.1.2.
User needs to unban 195.184.247.106 on their end, or wait for the ban
to expire, before the ship pages match reality.
