Improve UI · bjornmelin bundle
Read-only design-system drift audit: compare an implementation against its own documented design contract, prove each deviation, and plan verified refinements without replacing product identity. Scope is system consistency only -- it deliberately excludes accessibility, semantics, and copy, so it is not a general UI review. Use when asking whether a surface has drifted from the design system. For a holistic cross-discipline interface review use better-interface.
