Match the parametric ItemLightSystem instead of mounting a light per item:
a fixed pool of point lights is assigned to the nearest/most-visible lit
items each tick (camera-proximity scored, hysteresis, level factor), snapped
to each item's world position + offset, and faded on reassignment — so a large
house doesn't blow the renderer's light budget. The controls overlay already
mounts its <Html> only while the item sits in the focused zone (not hide/show);
add stopPropagation on the overlay so toggling a control no longer bubbles to
the canvas and deselects the zone.
