What specific challenge does your idea address?
Code hasn't gone through any testing for accessibility issues.

Describe the solution you'd like
Run through basic compliance testing using a tool like the WAVE accessibility checker, aXe, or Mozilla dev tools.

What other approaches have you considered?
Ignoring a11y, which is a nonstarter.
