## What it is
An Android library providing a card peek/pop controller built on ViewPager, letting cards expand into full views with front and back fragments. It works by extending ExpandingViewPagerAdapter and ExpandingFragment in your app.

## Use cases
- create expanding card layouts in an Android app
- add peek/pop card transitions to a ViewPager
- build card-based UIs with flip-to-detail fragments
- implement Material-style card expansion animations
- handle back-press to collapse expanded cards

## When to choose
- you need card peek/pop or expand transitions on Android 5.0+
- your app already uses ViewPager with fragments
- you want a small drop-in UI controller rather than a full framework

## When to avoid
- you need support for Android versions below 5.0
- you use RecyclerView or Jetpack Compose instead of ViewPager
- you need an actively maintained library with a license and recent releases

## Facets
