Smarter cache invalidation - only affected data refreshes.
Before: Some operations triggered broad cache clears.
Now: Surgical invalidation: Update category → Only that category + its products refresh (unrelated products untouched)
Benefits:
Faster edits - No waiting for full cache rebuilds
Relationship-aware - Invalidation logic understands data connections
Debug visibility - Cache hit/miss rates in developer tools
Dramatically improves the edit-preview-edit workflow during active development.
