ZPL Diff

Paste two versions of a label and see exactly what changed: both are rendered with the same size and resolution, the overlay marks removed ink red and new ink green, changed areas get a box, and a line diff of the formatted code shows the commands behind it - layout-only changes such as line breaks are ignored.
