💡 [Feature]: Implement PWA Support

[Papia-tech]

Objective:

Transform the web app into a Progressive Web App to enable offline access and "Add to Home Screen" functionality.

Key Tasks:

• Manifest: Add manifest.json (icons, theme colors, standalone display).

• Service Worker: Register a script for background asset caching.

• Offline Support: Implement a caching strategy (e.g., Stale-While-Revalidate) for core UI.

Benefits:

• Native Feel: Installable on mobile/desktop without an app store.

• Performance: Near-instant loading via cached assets.

• Reliability: Functional on weak or nonexistent internet connections.

Impact:

Improved user retention and a more professional, accessible mobile experience.

• I am a registered GSSoC 2026 contributor.
• I would like to implement this feature myself.
