## What it is
UPCarouselFlowLayout is a Swift library providing a custom UICollectionViewFlowLayout that renders a carousel effect with paginated scrolling. Side items are automatically scaled down and made transparent, with configurable spacing modes.

## Use cases
- build a paginated image carousel in an iOS app
- create a cover-flow style picker with shrinking side items
- add a horizontally scrolling card carousel to a collection view
- make a swipeable product gallery with faded side cards
- customize carousel item scale, alpha, and spacing in Swift

## When to choose
- you need a carousel effect on a UICollectionView with minimal setup
- you want configurable side-item scaling, transparency, and spacing modes
- you prefer a lightweight drop-in layout class usable from code or Interface Builder

## When to avoid
- you need a carousel outside of UICollectionView on iOS
- you target platforms other than iOS
- you need a fully custom animation beyond scale/alpha/shift effects
