- public/push-sw.js: shows the content-free push; tap focuses/opens the app.
- src/lib/pushService.ts + usePushNotifications: register the SW, subscribe with
the service's VAPID key, sign a NIP-98 challenge proof, POST /subscribe.
- NotificationSettingsCard: a 'Background notifications' toggle (opt-in,
per-device) + honest metadata copy; corrected the now-stale 'we run no push
server' note.
- useSendDirectMessage: marks the RECIPIENT wrap ["skatespots","push"] (never
the self copy) and adds the community relay as the notify relay so the push
service sees it.
- /privacy: discloses the push server sees metadata only.
