Second-pass a11y work across all 12 component groups. Every interactive element now has activeFocusOnTab, Keys.onReturnPressed/SpacePressed, and context-aware Accessible.name/description bindings. Highlights: - Dialogs: keyboard handlers with enabled-guard on confirm buttons - CDropdownMenu: full keyboard nav (Up/Down/Enter/Escape) - CLoginForm: explicit KeyNavigation.tab chain (username→password→submit) - CNotificationBell: dynamic "3 notifications"/"No notifications" name - CJobProgressBar: Accessible.minimumValue/maximumValue/currentValue - CExecutionStatusDot: "Execution status: Running/Passed/Failed" binding - CKeyboardShortcuts: invisible Repeater exposes all shortcuts to a11y tree - CDataTable rows: "Row N of M" descriptions - Canvas elements: Accessible.Canvas role + keyboard zoom (+/- keys) - DropdownExpandedList: focus-highlight extended to :activeFocus - Dynamic names reflect loading state (e.g. "Signing in, please wait") Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
