- FirstRunChecklist showed to any logged-in user until manually dismissed; it now
requires a recent signup_completed stamp AND first-run-seen (auto, once), so
established/imported accounts never see it.
- SignupDialog wrote the backup-confirmed flag under user?.pubkey while the login
was still settling, so it landed on 'backup-confirmed:anon' and the post-signup
BackupReminder nagged every session. Now markBackupConfirmed() is called with the
pubkey derived from the minted nsec.
- NIP-49 export password field autoComplete new-password -> off (fewer browser
save-password prompts).
A one-shot 'Get started' nudge on the map for freshly signed-up users: Add a spot / crew / wallet. The crew CTA adapts to whether any crew exists yet — 'Join a crew' (/crews) when there are some, 'Start your crew' (/create-crew) when there are none. Dismissal persists; logged-out visitors see the welcome banner instead.
