What's new
- Visual separation between the two columns — distinct styling makes the boundary unmistakable.
Before
After
- No re-reading the header — at a glance you know whether you're looking at your score or the aggregate.
Why it matters
Reviewers calibrate against the group score, but only after they've recorded their own. When the two columns look identical, people read the wrong one and either anchor too early or double-enter. A small layout change here removes a real source of evaluator error.
