-# AKSRT widget static accessibility audit
-
-Scope: `src/WidgetSystem/Renderers/`, `assets/widgets/frontend.js`, and `assets/widgets/frontend.css`.
-
-The source audit was repeated after remediation. Browser, screen-reader, Lighthouse/axe, console, and network validation remain pending until a target WordPress URL and browser MCP are available.
-
-## Critical (WCAG A)
-
-No static critical issue was found.
-
-## Serious (WCAG AA)
-
-No unresolved static serious issue remains.

-## Resolved source findings
-
-- **WCAG 2.1.1 Keyboard:** article and feature tabs now implement Arrow Left/Right, Home/End, focus movement, roving `tabindex`, and stable tab/panel associations.
-- **WCAG 2.4.7 Focus Visible:** all widget links, buttons, inputs, selects, textareas, and explicit tabindex targets receive high-contrast light, dark, and forced-colors focus rings.
-- **WCAG 2.2.2 Pause, Stop, Hide:** autoplay carousels pause on keyboard focus and expose a labeled, persistent pause/resume button; reduced-motion mode continues to disable autoplay.
-- **WCAG 4.1.3 Status Messages:** AJAX containers expose `aria-live` and `aria-busy`, loading skeletons use `role="status"`, and video failure uses an assertive alert.
-
-These contracts are enforced by `tests/widget-system/a11y-contract.test.cjs`.
-
-## Browser verification still required
-
-- Confirm Swiper-generated pagination bullets, disabled navigation states, and pause/resume behavior with the bundled runtime.
-- Verify 200% zoom, high-contrast mode, dark-mode contrast, focus order, and focus retention after AJAX replacement.
-- Run Lighthouse or axe and perform keyboard-only checks at 1440, 1024, and 390 px in light and dark modes.
