## What it is
An Objective-C category on UIViewController that replicates the semi-modal view with pushed-back stacked animation from National Geographic's Park Guides app. It is a small drop-in library (2 files) requiring no subclassing, supporting iPhone and iPad.

## Use cases
- show a semi-modal panel with stacked push-back animation in an iOS app
- present a partial-height modal view controller without subclassing
- add slide-up or fade transition overlays to any view controller
- implement a bottom sheet style picker inside navigation or tab bar controllers
- present a resizable semi-modal view that works with the keyboard

## When to choose
- you maintain a legacy Objective-C iOS app targeting iOS 5-9 and want a lightweight semi-modal animation
- you want a tiny drop-in category instead of a full modal framework

## When to avoid
- you are starting a new Swift or SwiftUI project - the library is unmaintained since 2016 and predates modern iOS APIs
- you need adaptive presentations or iOS 13+ sheet-style modals, which UIKit provides natively
- you need guaranteed license compliance - the repo lacks a clear LICENSE file despite claiming MIT
