Accessibility as code

Every control is reachable and named for VoiceOver and TalkBack in every locale the app ships, every target's own box is at least 44 pt, text grows to 200 % without clipping, every colour pair the UI and its canvases paint is declared once and meets WCAG 2.2 AA in every colour set, motion follows one live reduce-motion source, every swipe, drag or hold has a tap or a named action, custom canvases speak a summary, and overlays keep both screen readers inside. Scripts and tests prove what a machine can see; a human screen-reader pass covers the rest.
