Plain-text seed QRs didn't scan into Passport Prime — wallets that
import seeds by QR (Passport, SeedSigner, Keystone, Nunchuk, Sparrow)
expect the SeedQR standard: each BIP39 word as its zero-padded 4-digit
wordlist index, concatenated into a numeric QR.
- new utils/seedqr.ts encodes BIP39 words per the SeedSigner spec
(@scure/bip39 wordlist; vector-checked abandon=0000, zoo=2047)
- new shared SeedRevealPanel (Words/QR tabs, tap-to-reveal blur) now
backs the LND reveal AND the Settings→Backup recovery-phrase reveal,
so every current and future seed reveal behaves the same
- onboarding seed + Settings reveal: QR defaults to SeedQR with a
plain-text toggle
- LND seed stays plain-text-only with an explicit note: aezeed is not
BIP39 and only restores into LND-based wallets (Zeus/Blixt/another
node) — SeedQR-encoding it would just mislead

The full backup carried identity/lnd_aezeed.enc but NOT the per-node
wallet secret that encrypts it (secrets/lnd-wallet-password), so a
restored node could never decrypt its Lightning seed. The secrets dir
now rides the backup (archive v3; the .bak itself is
passphrase-encrypted). Restore gains a staging-presence guard so
restoring an older archive without a secrets dir can no longer displace
and delete the node's live secrets — covered by two new tests.
Backups can now also be downloaded through the browser: a session-gated
GET /api/blob/backup/<id> endpoint (under the existing nginx /api/blob
prefix, so no fleet nginx changes) plus a Download button next to
Verify / USB / Restore / Delete in Settings → Backup & Restore.
