/**

|
* Translucent ghost of a downspout — same geometry as the committed
|
|
* pipe so the placement ghost matches what lands on click. No
|
|
* internal transform wrapper; the placement tool nests this under
|
|
* the gutter / outlet chain so the position math stays in one place.
|
|
*
|
|
* `routing` mirrors the renderer's — when the tool resolves the host
|
|
* gutter it feeds the same wall-jog so the ghost already shows the
|
|
* elbowed path, not a straight drop.
