Bug: When user selected "Region 1" and edited box position, it was actually
moving Region 2's box instead.
Root Cause: transformFunc was using region selector value directly as array
index without converting from 1-based UI to 0-based array indexing.
- Region selector displays: "Region 1", "Region 2", etc. (1-based for users)
- Behind the scenes: array[0], array[1], etc. (0-based for storage)
Fix: In transformFunc, subtract 1 from region selector value before using as
array index:
regionSelectorValue = 1 → arrayIndex = 0 → updates array[0] (Region 1)
regionSelectorValue = 2 → arrayIndex = 1 → updates array[1] (Region 2)
Now editing "Region 1" box correctly updates the first region in the array.
