The window/door root is an invisible hitbox the system gives full-depth
BoxGeometry; its front face intercepted every paint/hover ray, so the hit
resolved to the hitbox (no slotId) → role null → paint silently disabled.
Disable the hitbox's own raycast in the visual path so R3F's recursive
intersect returns the tagged frame/glass (panel/glass) children instead;
selection still works because those child hits bubble to the root's event
handlers. Restored to the default raycast each build, and kept for 'opening'
windows/doors (no visuals to paint, still need a selectable hitbox). The
'cutout' child is visible=false so the raycaster already skips it.
