What it does (for your users):

Overlap check (isOverlappingBox): blocks new boxes if they geometrically overlap existing ones.
Proximity check (isTooCloseBox): blocks near-duplicates within zoneProximityPct.
Confluence detection (isBoxConfluent / getConfluenceBoxes): a box is confluent only if another box with different bounds strictly overlaps it (self is skipped).
Creation (createBox):
If no overlap and not too close → create normal box.
If overlap or too close → recolor the existing overlapping/near boxes to the confluence color; do not add a new box.
Enforces capacity and deletes broken boxes against direction.
Maintenance (manageBoxes): keeps boxes aligned to the latest bar and removes invalidated boxes.
