…ypt#1198) - Add LiveValue throttled aria-live region for ticking balances (IncomingStreamCard claimable, stream-details StatCard claimable) so screen readers announce on user query rather than per frame. - Respect prefers-reduced-motion in useStreamingAmount: compute accrued value once instead of running the rAF loop. - Global :focus-visible outline token for keyboard users (2.4.7). - Fix dark-mode contrast for ticker labels, badges, and modal copy (slate/emerald/amber/indigo utilities get dark: variants). - give the clipboard icon button in StreamDetailsModal an accessible name. - Replace invalid dl/dt/dd layout in IncomingStreamCard with div-based structure to satisfy axe definition-list/dlitem rules. - Add axe-core a11y suite (a11y.test.tsx) asserting zero critical/serious violations across IncomingStreamCard, StreamDetailsModal, TopUpModal, WalletModal; unit tests for LiveValue throttling.
