* Wraps a placement tool's preview/ghost so it rides the active level's
|
|
* stacked elevation.
|
|
*
|
|
* Placement tools are mounted inside the building-local group (see the editor's
|
|
* ToolManager), which carries no per-floor elevation. But their points, ports,
|
|
* and committed paths are level-local (Y=0 = the floor) and the committed nodes
|
|
* parent to the level mesh, which DOES carry the stacked Y offset. Without this
|
|
* the ghost renders at world ground on upper floors while the cursor raycast
|
|
* rides the floor plane — they drift apart. Tracking the level mesh's Y here
|
|
* (the same value the grid plane follows) keeps the preview on the floor being
|
|
* drawn, with no change to any tool's level-local math.
