Summary

• Name the six settings toggles with aria-labelledby pointing at the translated row label, replacing an aria-label on the wrapping <label>, where ARIA prohibits it and the checkbox resolved an empty name.

• Link every inline-edit field to its row label in initInlineEdit, and accept a function placeholder so a translated one is resolved on use rather than at wiring time, before the catalog is fetched.

• Lift each --chip-*-fg toward a per-theme --chip-ink-boost and give the unselected filter chip its own ink, clearing 4.5:1 for all six type pills and the chip on both the pane and a card in both themes.

• Raise the digital clock's date line to 0.55 alpha in both modes, from 3.54:1 dark and 2.30:1 light.

• Resolve color-mix() in the contrast test's token resolver, add tintOver to composite a translucent fill over a backdrop, and pin the seven tinted pairs against --pane and --cp.

• Wrap the settings content pane in <main>, and make the dashboard pager a <nav> landmark.

• Add uniqueTitle and number repeated widget frame titles in both dashboard builders.

• Build the books shelf as a <ul> of <li> spines nested inside the shelf, with the ledge strips as siblings; declare the list role only while populated.

• Inset the books hover panel to the tile's padding with a corner radius, and raise its type from 11/10/9px to 13/11/10px.

• Route the accessible names in the GitHub, Disk Health, Now Playing, Connections and Dashboard Switch widgets through wt(), with catalog entries in all six locales.

• Mark every dashboard page but the current one inert, on the home pager and in the folder overlay, so Tab cannot reach tiles that have scrolled off screen.

• Widen the pagination dot gap to 16px, giving a 24px pitch: an interior dot's hit area is bounded by its neighbours', so the pitch was its effective width.

• Remove the live region from System Summary, Weather, DNS and Now Playing, which announced their polled figures on a timer rather than after a user action. The text stays in the document and a widget-live-regions ratchet lists the three that a user action still fills.

• Add ACCESSIBILITY.md stating the target standard, the partial-conformance status, the known limitations, and the assessment method, linked from the README.

• Read the Move up and Move down button names from the catalog, and send the GitHub pull request filters as keys so the page names them from translations its catalog already held.

Testing
All green. Added control-names, landmarks and books-list-semantics suites, extended the contrast test with the tinted pairs, and verified the result with axe-core in Chromium and WebKit against a container: settings reports zero violations across all four sections and both viewports, down from two to three each. Scanned all 14 widget documents. Also checked reflow at 320px, resize to 200%, text spacing, target size by hit-testing, and a 40-stop keyboard walk across a three-page dashboard.

Checklist

• Stays within the project constraints: one container, no runtime dependencies, no build step (see CONTRIBUTING.md).
• Tests added or updated for new logic, and the full suite, lint, and typechecks pass.
• Docs updated if behavior or configuration changed.
• CHANGELOG.md updated under Unreleased if the change is user-visible.
