Rebuilding interfaces loses interactive details that static comparisons cannot capture

Replacing an existing interface through large-scale refactoring loses carefully crafted interactive behaviors that cannot be verified through static side-by-side image comparisons.
Engineers rebuilding interfaces often verify completeness by comparing old and new designs as screenshots, but this method cannot confirm that interactive behaviors and edge-case handling survive the transition. The result is invisible regression, where years of use-case-driven refinements disappear without anyone noticing.

Static side-by-side image comparisons of interfaces cannot capture the interactive behaviors that define how features actually work.
Large-scale refactors are bulldozing interfaces and losing tiny details that were crafted over years with specific rationales tied to real-world use cases.
Few people notice what has been lost because few could see the interactive subtleties in the first place.
