 * Click-place tool for duct fittings (elbow / tee / reducer).
 *
 * A translucent ghost of the fitting follows the cursor. Within snap
 * range of any scene port (duct run ends, other fittings' collars) the
 * ghost jumps onto the port — position AND orientation — so one click
 * mates the fitting onto the run.
 *
 * Rotation while placing: **R / T** turn the ghost ±45° around the
 * active world axis; **Alt** cycles the axis (Y → X → Z). The HUD badge
 * above the ghost shows the current axis. When snapped to a port the
 * rotation pivots around the inlet collar so the joint stays mated.
 * Handlers run in the capture phase so R doesn't also spin whatever
 * node happens to be selected.
