Artwork bounds
Artwork bounds are the smallest declared rectangle used to size and place an item. They may follow visible or thresholded pixels rather than the original canvas. Oversized transparent padding or remote low-alpha debris enlarges the rectangle, which can waste space even when the main design looks tightly cropped.
In practice
Bounds are a geometry contract, not an artistic verdict. Intentional shadows and fades may belong inside them; alpha-zero padding usually does not. Record which threshold or trim rule produced the rectangle before comparing layouts.
NestSheet currently packs rectangular item bounds. Cleaning or trimming a source can therefore change placement, but it must not silently change the approved physical size or remove intended soft content.
