Overview
Modernized the service worker to handle fingerprinted assets and surface a polite update prompt.
The Challenge
Stale caches and outdated asset paths broke offline support and confused users.
The Approach
- Static list replaced with cache-by-prefix for
/css/and/js/. - Added updatefound banner wiring with SKIP_WAITING.
- Network-aware guard to skip SW on localhost and slow connections.
The Outcome
Reliable offline behavior, clearer updates, and fewer cache-related support pings.
