14 April 2026	in-progress	on-track	TThe test library itself has gone through a few iterations and the MVP is in review in this PR. Once we get approval on the library, we can start using it to generate component test lists and run baseline audits on our components. I also want to start refining some skills and prompts that use this library for things like improving our our e2e test coverage, but that can come later. Next: Have Jeana and I build component test files (and continue to refine our prompt/docs for that process) Start running those component tests for a baseline audit. I'd like to see if we can have other folks on the team do at least some of these audits to test the clarity of the library and start distributing hands-on a11y time across the team
