Visual bugs after release are expensive and avoidable.
Post-release visual feedback from stakeholders means unplanned rework. A component ships with the wrong font weight. A spacing decision gets misread. A colour is off by enough to notice. None of these are blockers. They surface after release.
The fix is a verification step before sign-off. But manual visual review is inconsistent and depends on whoever has time to do it. Some things get caught. Others don't.
Uiprobe gives the team a repeatable check that doesn't require a process overhaul.
