PR Summary

For every new or refreshed PR, use pr-writer for the title and standard description when it is available, then place this block at the very top of the PR body:

## Summary

- **Before:** <the problem, missing capability, or limitation before this PR>
- **After:** <the behavior or state reviewers should expect after this PR>
- **Solution:** <the main implementation approach taken by this PR>

Derive all three statements from the verified issue or specification and the current base-to-head diff. Keep each statement to one concise sentence when possible. For a refactor with no intended behavior change, say so explicitly in After and describe the structural improvement in Solution.
