 *
 * The tree is document-grain and **unversioned**, so changes here write
 * immediately (independent of the form's content save). The editor picks a
 * parent through the collection's own relation picker — same search / columns
 * UX as a relation field — or moves the document to the top level; the server
 * enforces the cycle / same-collection invariants and fires the
 * structural-change invalidation event.
 *
 * Renders only in edit mode (placement needs a persisted document) and only when
 * the host wires the tree services. Stable override handle: `.byline-form-tree`.
