Mirrors the activity the app already computes (bell, crews, DMs, newsletter) to the OS notification shade, with no new relay traffic and no new network destination. - src/lib/osNotify.ts: one delivery API. Web uses the Notification API; native uses @capacitor/local-notifications (lazily imported, so the web bundle never pays for it). Tap-through navigates in-app. - src/components/OsNotificationBridge.tsx: mounted once in Layout, inert until opted in. Per-source silent priming + a seen-id set means history is never replayed as a flood, and it stays quiet while the app is visible (the bell already covers that). - DMs notify from the gift-wrap ENVELOPE only (src/hooks/useDmEnvelopes.ts, no decryption) — so Amber is never prompted just to be told you have a message. Preview is honestly generic. - src/lib/notificationPrefs.ts + useNotificationPrefs: device-local, opt-in, default off, per-category toggles. Settings -> Notifications UI. Deliberately local-only: a fully closed app needs a server push, which is not built (Phase 2 = on-device background runner; Phase 3 = content-free FCM).

/**
|
|
* Lightweight DM "envelope" watcher — the id and timestamp of every NIP-17 gift
|
|
* wrap addressed to the user, **without decrypting anything**.
|
|
*
|
|
* This is what makes DM notifications possible without ever prompting Amber:
|
|
* the seal/rumor are encrypted, so we only see that *something* arrived. No
|
|
* sender, no content, no signer round-trip. The preview is intentionally generic
|
|
* ("New direct message") — the honest ceiling when we refuse to decrypt in the
|
|
* background.
|
|
*
|
|
* NIP-17 randomises the outer wrap timestamp (up to 2 days in the past), so we
|
|
* cannot reliably tell "new" from `created_at`. Callers should diff on the
|
|
* stable `id` instead.
