The crosshair answers before the click commits

Hovering the pane now shows what a click would do: a wizard or
creature outlines in gold with its name at the crosshair, a wall or
door face lights across every column it owns, and a floor square
draws its perspective-true quad on the ground. Warp-bent ground still
targets truly but labels itself "through the warp" rather than
drawing a quad in the wrong geometry. And when a cell-target card is
selected, the ineligible ground dims in the 3D view itself — the same
litCells the board's shadow uses, rasterized into the floor pass.
