Dropped treasure is seen falling

treasureDropped and objectDropped played as nothing — the gold simply
teleported from chest to floor between frames. A drop now glints (the
spark blooming where it lands, a beat after the blow when combat
knocked it loose), and a wizard dropping at their own feet takes the
cutaway: a third-person shot of them setting the prize down — or
spilling it. When the reel's wizard strikes the spill loose from
someone else, the attack-facing already has the victim in frame, so
the treasure falls on camera.
