WCAG 2.2 Level AA is the release target. This page describes the target and implementation provisions; it is not a third-party conformance claim.
Target browsers
The target is the latest two stable major releases of Chrome / Edge, Firefox, and Safari at release time.
Target operating systems
The target is Windows 11, macOS 14 or later, iOS 17 or later, and Android 14 or later.
Assistive technology under test
VoiceOver + Safari and NVDA + Chrome / Firefox are the test targets.
Known limitations
Canvas output depends on browser codec support. When an optional codec is unavailable, the app shows a supported-format error.
Conformance review date
Not established. This will be updated after implementation, axe, Lighthouse, keyboard, VoiceOver, and NVDA checks are complete.
Response target
