Introducing @accesslint/jest: progressive accessibility testing for Jest

This post is for the team rolling out accessibility testing: developer tooling, CI platform, design systems, frontend tooling, or their engineering managers. Enabling accessibility tests on greenfield code is straightforward. On an existing codebase it's harder: the suites typically contain hundreds or thousands of known violations no team has prioritized. Teams have typically tried four approaches and watched each erode. Gating on zero turns CI red across the suite. A suppressions file decays a
