## What it is
Threlte is a declarative, type-safe 3D framework for Svelte that wraps Three.js with reactive components. It ships as modular packages including physics via Rapier, animation via Theatre.js, XR support, and a GLTF-to-components CLI tool.

## Use cases
- build interactive 3D scenes in Svelte
- add physics to a web 3D app
- create VR and AR experiences in the browser
- convert GLTF models into reusable Svelte components
- animate 3D scenes with Theatre.js
- render 3D product configurators on the web

## When to choose
- you use Svelte and want declarative Three.js bindings
- you want type-safe, reactive 3D components with interactivity out of the box
- you need integrated physics, animation, or XR in a Svelte app

## When to avoid
- your project uses React or another framework (use react-three-fiber instead)
- you need raw imperative control over the Three.js renderer
- you are building a non-web native 3D application
