//    handles.
//  - `MoveTool` runs the kind-owned mover once a translate handle arms
//    `useEditor.movingNode`.
//  - `ToolManager` mounts the active registry build tool (wall / door / window /
//    …) for interactive placement when `useEditor` is in build mode with a
//    tool, plus the snap/alignment guide layers. Mount it only while a tool is
//    active to avoid its select-mode boundary editors.
//  - `Grid` is the interactive drafting plane: it raycasts the pointer and
//    emits the `grid:move` / `grid:click` events the build tools consume (the
//    wall tool is driven entirely by them; door/window use them for free-follow
//    alongside the viewer's `wall:*` mesh events). Without it the tools mount
//    but their cursor never tracks the pointer. Mount it while a tool is active.
// All read `useViewer` selection + `useEditor` state, and cooperate with host
// camera controls via the `useViewer.inputDragging` / `useEditor.movingNode`
// flags. Tools place onto `useViewer.selection.levelId`, so the host must set a
