Helps new users quickly understand what the output of the demo looks like, improving clarity and onboarding experience.

Hi @MANKINGS999 — thank you, this is a good first visual contribution.

The screenshot itself is useful. To make the PR complete for onboarding, could you add one small README reference to it?

Suggested minimal follow-up:

### PR review trail demo screenshot

A good place would be near the existing PR-review trail demo commands in README.md, close to:

Run the PR-review trail demo

or near the first 10 seconds / demo section.

Please keep it small: just the screenshot reference and maybe one sentence explaining what the image shows. No need to redesign the README.

Thanks again — this is exactly the kind of small visual proof point that helps new visitors understand the project faster.

Thanks! I’ve already added the screenshot reference near the PR-review trail demo section in the latest commit. The image should now render correctly in the README preview.

Thanks @MANKINGS999 — I checked the current PR head again.

GitHub still shows only one changed file:

assets/pr_review_demo.png

I don’t see the README.md update in the PR yet, and the PR head SHA still appears to be the earlier screenshot-only commit.

Could you please push the latest commit that adds the README reference?

Expected small diff:

Once that README commit appears in the PR, this should be ready for review. Thanks again — this is very close.
