From 54c355f6f84a6fa778807400466760bed1c68bc9 Mon Sep 17 00:00:00 2001 From: water <672684719@qq.com> Date: Sun, 9 Aug 2026 04:00:33 +0800 Subject: [PATCH] feat(dispute-card): add aria-live region for polite status announcements Adds a LiveRegion (aria-live="polite" / role="status") to DisputeCard that announces the current dispute state whenever the resolved state changes. This ensures screen-reader users are notified of state transitions.
