Hi! Thanks for the contribution. The full-page screenshots are a great start!

To make the README even more impactful, could you refine the visuals to focus on the core features? I’d like to showcase the Comparison Tables and the Analytics Chart specifically, as these are the main highlights of the UI.

Could you please update the PR with the following:

Focused Screenshots: Instead of the whole page, capture a clear shot of just the section containing the comparison tables and the chart.

Top Placement: We will place the screenshot at the top of the README.md so users see the UI immediately.
