Deployment Notes

Cache Invalidation

The service worker uses versioned cache names to ensure users get fresh content after updates.

Before each deployment:

1. Update the cache version in public/sw.js:

const CACHE_NAME = "bandcrawl-vX"; // Increment X

1. The service worker will:
2. Install with the new cache version
3. Delete old cache versions on activation
4. Force clients to use the new cache
