@MKNas01 has applied to work on this issue as part of the Stellar Wave Program's 8th wave.

I’d like to work on #782 because it provides a focused way to improve the project’s accessibility while also making WCAG compliance part of the development workflow. I’ll integrate axe-core into CI to scan the main frontend pages, configure the workflow to fail on critical or serious violations, and upload a clear report containing the affected page, violation details, elements, and color-contrast issues. I’ll first review the existing frontend/testing and CI setup to follow the project’s conventions, add the necessary tests and workflow changes, verify the audit locally, and ensure the CI job behaves correctly for both passing and intentionally failing accessibility cases. I’ll also update the relevant documentation if needed and keep the implementation scoped to the issue so it is reliable and easy to maintain.
