## What it is
A React component and hook that work around the '100vh' viewport height issue in mobile browsers like iOS Safari. It provides the real visible viewport height so full-screen layouts aren't cropped by browser chrome.

## Use cases
- fix 100vh cropping on mobile safari
- make full-screen splash page in react that fits mobile viewport
- keep call-to-action button visible above mobile browser toolbar
- get real viewport height in pixels in react
- app-like full height layout on mobile web

## When to choose
- building React apps where full-height layouts get cropped by mobile browser chrome
- you need a simple drop-in component or hook for accurate viewport height

## When to avoid
- desktop-only web apps where 100vh works fine
- non-React projects (though measureHeight is usable standalone)
- projects already using modern CSS solutions like dvh units
