#1040 Add progressive web app (PWA) support

[vic-Gray]

Area: frontend · Effort: M

What: Add service worker, web app manifest, and offline capability to the Next.js frontend to enable PWA installation on mobile devices.

Why: PWA installation on the home screen dramatically increases retention compared to browser-only access. This is especially impactful for the mobile-first Nigerian market.

Acceptance Criteria:

• Web app manifest defines name, icons, theme colour, and display mode
• Service worker caches static assets and last-seen vault list for offline viewing
• PWA installation prompt is shown to eligible users after 3 visits
• Lighthouse PWA score is ≥ 90

Hints:

• Use next-pwa plugin for automatic service worker generation
• Icon sizes: 192×192 and 512×512 in PNG format
• Offline fallback page at /offline.html

Hi 👋

I’d like to add PWA support to the frontend.

I’ll integrate next-pwa, set up the web app manifest (icons, theme, display), implement service worker caching for assets and vault data, and add an install prompt after repeat visits.

This should improve mobile retention and enable offline access 📱
