## What it is
Carbon is a Material Design implementation library for Android 4.0+ that provides real backports of Lollipop features like animated shadows, touch ripples, rounded corners, and vector/SVG support. It offers custom widgets, XML attributes for styling, and bugfixes to make UI look consistent across all Android API levels.

## Use cases
- add material design shadows and ripples on pre-Lollipop Android
- backport elevation and rounded corners to Android 4.x
- use material widgets like BottomNavigationView and TabLayout on old APIs
- render SVG vectors with gradients and text in Android views
- apply custom fonts and tinting consistently across Android versions
- fix Android layout bugs like FrameLayout padding handling

## When to choose
- you must support old Android versions (4.x) with modern Material Design looks
- you want consistent shadows and ripples across all API levels without gradients
- you need extra widgets like RangeSeekBar, FlowLayout, or FloatingActionMenu

## When to avoid
- you target only Android Lollipop and above and can use native Material Components
- you need a library under active development with recent updates
- you prefer Jetpack Compose over XML-based Android UI
