/**
 * Convenience hook to use animations loaded with the `<GLTF>` component or the
 * `useGltf` hook.
 *
 * Pass `gltf` as a getter so reads are tracked through runes automatically.
 * The optional `root` getter binds animations to a different `Object3D` than
 * the gltf's own scene — useful when retargeting clips onto a separate rig.
 *
 * ### Example with `useGltf`
 *
 * ```svelte
 * <script lang="ts">
 *   import { useGltf, useGltfAnimations } from '@threlte/extras'
 *
 *   const gltf = useGltf('/Bengal.glb')
 *   const { actions } = useGltfAnimations<'Run' | 'Idle'>(() => $gltf)
 *
 *   $effect(() => {
 *     $actions.Run?.play()
 *   })
 * </script>
 * ```
 *
 * ### Example with `<GLTF>` and `bind:gltf`
 *
 * ```svelte
 * <script lang="ts">
 *   import { GLTF, useGltfAnimations, type ThrelteGltf } from '@threlte/extras'
 *
 *   let gltf = $state<ThrelteGltf | undefined>()
 *   const { actions } = useGltfAnimations<'Run'>(() => gltf)
 * </script>
 *
 * <GLTF url="/Bengal.glb" bind:gltf />
 * ```
