 * Merge several partial visitors into one. When multiple visitors share a node

 * them to observe the same nodes.
 *
 * `visitors` is intentionally loose: each module's handlers carry their own
 * narrowed `NodePath<T>` signatures, which are incompatible with a single
 * generic `Handler` under strict checks.
