- manifest.json (standalone display, theme color, maskable icons 192/512).
- generated square icons + apple-touch-icon (180) from the logo.
- apple-mobile-web-app + theme-color meta in home.html.
- sw.js gets a no-op fetch handler so it meets installability criteria (still
no caching). static.js serves .json/.webmanifest with correct MIME.
- Installing as a PWA also unlocks Web Push on iOS (Apple requires Add to Home Screen).
Build marker -> pwa1.

Page-level Notifications can't fire when a tab is frozen/closed (and never on
mobile), which is why recipients on another tab/app got nothing. Adds a
notification-only service worker (sw.js, no caching) + Web Push:
- push.js: optional web-push wrapper (no-op unless web-push installed AND
VAPID_PUBLIC_KEY/VAPID_PRIVATE_KEY set -> app unaffected if unconfigured).
- push_subscriptions table + R.pushSubs repo (upsert by endpoint, prune dead).
- /api/push/vapid|subscribe|unsubscribe; DM + group message routes also send a
Web Push to recipients.
- Client registers /sw.js, subscribes when permission granted; hidden-tab popups
are left to push to avoid double-notifying (pushActive flag); SW suppresses the
OS popup when a tab is visible. Removes the old code that unregistered SWs.
Requires (prod, once): npm install + VAPID_PUBLIC_KEY/VAPID_PRIVATE_KEY/VAPID_SUBJECT env.
