## What it is
Cloudy is a Kotlin Multiplatform library for Compose that provides blur, liquid glass, and shader-driven surface effects via simple Modifier extensions. It uses GPU-accelerated rendering with a CPU fallback for older devices.

## Use cases
- blur a composable's own content in Jetpack Compose
- create glassmorphism backdrop blur effects behind UI elements
- add liquid glass lens effects with refraction and chromatic dispersion
- apply custom shader effects like thin-film or specular highlights
- support blur on older Android devices without RenderScript
- blur network-loaded images in Compose

## When to choose
- you're building Compose or Compose Multiplatform UIs and need blur or glass effects
- you need cross-platform (Android + other KMP targets) surface effects
- you must support older Android versions lacking native blur APIs
- you want customizable shader effects beyond simple blur

## When to avoid
- your project doesn't use Jetpack Compose or Kotlin Multiplatform
- you only target iOS or non-Android platforms without Compose
- you need image-processing blur on saved files rather than UI rendering
- you're on a platform where GPU/CPU fallback performance is insufficient
