/**
 * Gathers every animation clip below a root, bound to the objects it animates.
 *
 * Both exporters take a root and its clips separately, and resolve each track
 * against the subtree they are handed. Clips therefore reach a file only when
 * they are passed at the top level -- ones sitting on a descendant's
 * `Object3D.animations`, or held by a component, are invisible to the export.
 *
 * Two places are read, because that is where clips end up: `Object3D.animations`,
 * which the asset loader fills for a plain load, and the `animations` field of a
 * component, which is where {@link ModelComponent} keeps them. Components are not
 * part of the graph, so a traversal alone never reaches them. Matched
 * structurally, so a component added later that carries clips needs no change
 * here.
 *
 * Each clip is bound to the objects of the asset that holds it, which is why this
 * cannot live in the exporter: only the holder knows which objects its clips
 * belong to, and by the time a whole scene is handed over, that pairing is gone.
 *
 * @param root - The object to collect below.
