## Why Caching Matters More Than You Think

Without caching:

* Every screen → API call
* Every interaction → network delay
* Every reload → fresh fetch

Result:

* Slow UX
* High server load
* Poor scalability

With caching:

* Instant data
* Reduced network calls
* Smooth experience

## The Real Problem

Most frontend apps:

* Fetch too o
