# Browser Screenshot Diff
Compare two recorded sessions step-by-step. Pairs each step in session A to the same `step-id` in session B, diffs the captured screenshot and accessibility snapshot, reports the first divergence and an aggregate similarity score.
## When to use
- Visual regression after a UI change (record before, record after, diff).
- Verifying a `browser-replay` run matches the parent session within tolerance.
- Comparing two A/B variants of the same form flow.
## Steps
1. **Locate both RVF containers**:
```bash
