These toggles are a first-party enhancement layered on top of markup we build to follow WCAG 2.2 Level AA guidance — they are not a substitute for accessible design, and we have not undergone a formal third-party compliance audit, so we don't claim full conformance. If you hit a real accessibility barrier anywhere on this site, please open an issue — we'd rather hear about it than have this panel stand in for fixing it.
