Sets layers on root and every descendant (§46) — the subtree spelling that
self-only semantics makes explicit rather than implicit (see the module
header).
applyLayers(panel, layerMask("ui")); // the panel and everything in it
Depth-first in insertion order, like every other walk in the engine, and it
writes nothing else — a node's transform, visibility, and components are
untouched. Idempotent, so calling it after adding a child re-establishes the
subtree's membership without any bookkeeping in between.
It walks every node, cameras included — and Camera.layers is the mask
that camera looks at, not one it belongs to (see camera.ts). Applying
layers to a subtree containing a camera therefore re-aims that camera. Apply
to the branch you mean.
Takes the node structurally rather than as a Node, so node.ts can import
this module for DEFAULT_LAYER_MASK without closing a cycle.
